Unisex Shoe Size Chart: Can Women Wear Men’s Sneakers? 2026 Guide
Women can wear men’s and unisex sneakers when the shoe has the right length, width and overall fit. A 1.5-size US conversion is a useful starting point for many athletic shoes, but the exact size should be confirmed with the manufacturer’s current chart.
Yes, women can wear men’s sneakers. The important part is choosing the correct US size, foot length, width and shoe shape.
For many US athletic shoes, a common starting point is a 1.5-size difference between women’s and men’s sizes. For example, a US Women’s 8.5 commonly corresponds to a US Men’s 7 on Nike’s current men’s-based unisex chart. But this is a starting point, not a universal rule for every brand or model.
This unisex shoe size chart explains the women’s-to-men’s conversion, how to measure your feet, how Nike and adidas handle sizing, what “unisex” means, and how to check the fit before buying.
Quick answer: Start with the brand’s conversion chart, measure both feet, use the longer foot measurement, and check width before ordering.
Unisex Shoe Size Chart: Women’s to Men’s Conversion
Use this table as a US conversion starting point when shopping for men’s or unisex athletic shoes.
| US Women’s | US Men’s | Common Conversion |
| 5 | 3.5 | -1.5 |
| 5.5 | 4 | -1.5 |
| 6 | 4.5 | -1.5 |
| 6.5 | 5 | -1.5 |
| 7 | 5.5 | -1.5 |
| 7.5 | 6 | -1.5 |
| 8 | 6.5 | -1.5 |
| 8.5 | 7 | -1.5 |
| 9 | 7.5 | -1.5 |
| 9.5 | 8 | -1.5 |
| 10 | 8.5 | -1.5 |
| 10.5 | 9 | -1.5 |
| 11 | 9.5 | -1.5 |
| 11.5 | 10 | -1.5 |
| 12 | 10.5 | -1.5 |
Example: If you normally wear a US Women’s 9, start by checking a US Men’s 7.5.
However, always compare the result with the manufacturer’s current size chart. Nike’s current men’s-based unisex chart, for example, lists US Men’s 7 alongside US Women’s 8.5.
Important
This table is a quick US conversion reference, not a replacement for a brand-specific size chart.
If the manufacturer’s chart gives a different recommendation, use the manufacturer’s chart.
What Does Unisex Mean in Shoe Sizing?
Unisex shoes are designed to be offered to people of different genders, but “unisex” does not automatically mean men’s sizing.
A brand may provide:
- A men’s-based unisex chart
- A women’s-based unisex chart
- Men’s and women’s equivalents
- One shared size scale
- Model-specific measurements
Nike is a good example. Its current site provides a Unisex Shoes (Women’s Based) chart as well as men’s-based footwear sizing information.
That means you should not see “unisex” on a product page and automatically assume:
Unisex = Men’s
Instead, look at the actual size chart attached to the product.
Can Women Wear Men’s Sneakers?
Yes.
A woman’s gender does not prevent her from wearing a men’s sneaker. The relevant questions are whether the shoe has:
- Enough length
- Suitable width
- A secure heel
- Comfortable toe-box space
- The right shape for the foot
- Appropriate construction for the intended activity
This can be particularly useful when a preferred colorway, size or model is only available in men’s sizing.
For example, if your normal size is US Women’s 8.5, a men’s-based chart may direct you toward US Men’s 7.
But don’t stop at the numerical conversion.
How to Convert Women’s to Men’s Shoe Sizes
For many US athletic shoes, the common starting formula is:
US Women’s size – 1.5 = US Men’s size
Example 1
Women’s 8.5:
8.5 – 1.5 = Men’s 7
Example 2
Women’s 9:
9 – 1.5 = Men’s 7.5
Example 3
Women’s 10:
10 – 1.5 = Men’s 8.5
The important point is that this formula should be treated as a conversion shortcut, not a universal sizing law.
For the final choice, use the brand’s chart.
Women’s to Men’s Shoe Size Chart
| Women’s US | Men’s US |
| 5 | 3.5 |
| 5.5 | 4 |
| 6 | 4.5 |
| 6.5 | 5 |
| 7 | 5.5 |
| 7.5 | 6 |
| 8 | 6.5 |
| 8.5 | 7 |
| 9 | 7.5 |
| 9.5 | 8 |
| 10 | 8.5 |
| 10.5 | 9 |
| 11 | 9.5 |
| 11.5 | 10 |
| 12 | 10.5 |

How to Measure Your Feet for a Unisex Shoe
A size conversion becomes much more useful when you know your actual foot length.
Nike’s current instructions recommend placing paper on a hard, flat surface, standing on it, marking the longest toe and heel, measuring the distance, repeating the process for the other foot, and using the longer measurement with the size chart.
Simple measuring method
- Place a sheet of paper on a hard floor.
- Stand naturally with your weight evenly distributed.
- Mark the back of your heel.
- Mark the end of your longest toe.
- Measure between the two marks.
- Repeat for the other foot.
- Use the longer measurement when following the manufacturer’s chart.
Why measure both feet?
Your feet may not be exactly the same length.
If one foot measures 25.0 cm and the other measures 25.3 cm, don’t choose a size based only on the smaller foot.
Follow the manufacturer’s instructions and use the longer measurement where recommended.
Don’t Treat the CM Number as a Universal Shoe Length
A common mistake is assuming that a CM number printed on a shoe box is always an exact measurement of the wearer’s foot.
Nike specifically states that the CM size displayed on shoe boxes and labels is different from Foot Length (cm).
So don’t use this shortcut:
My foot = 25 cm → every shoe labeled 25 cm must fit
Instead:
Measure your foot → check the manufacturer’s chart → choose the corresponding size
This distinction is especially useful when comparing different brands.
Nike Unisex Shoe Sizing
Nike provides official size charts that show how its men’s and women’s footwear sizes correspond.
Its current men’s-based unisex chart includes both US Men’s and US Women’s sizes along with UK, EU, CM/JP and foot-length information.
For example:
US Men’s 7 = US Women’s 8.5
The same Nike chart also explains how to measure foot length and recommends using the longer of the two foot measurements.
Nike width matters too
Nike’s current chart distinguishes regular, wide and extra-wide shoes. Its guidance says wide shoes have approximately 6.35 mm more toe-box girth than regular-width shoes, while extra-wide shoes have approximately 1.27 cm more.
That is a useful reminder:
A size conversion does not tell you the whole fit story.
adidas Shoe Sizing
adidas publishes a men’s and women’s footwear chart that includes US, UK, EU, JP and heel-to-toe measurements.
This is important because it shows why a generic conversion formula should not be treated as a universal rule.
The current adidas chart gives the actual heel-to-toe measurement associated with each listed size.
For example, adidas lists:
| Heel-to-toe | US Men’s | US Women’s |
| 24.6 cm | 7 | 8 |
| 25.0 cm | 7.5 | 8.5 |
| 25.5 cm | 8 | 9 |
| 25.9 cm | 8.5 | 9.5 |
| 26.3 cm | 9 | 10 |
Always check the current adidas chart for the specific purchase because the manufacturer’s own measurement system should take priority over a generic online conversion table.
Nike vs. adidas: Why Brand Charts Matter
| Factor | Nike | adidas |
| Men’s/women’s comparison | Published in official charts | Published in official chart |
| Foot measurement | Foot Length | Heel-to-toe |
| US sizes | Yes | Yes |
| UK/EU sizes | Yes | Yes |
| JP/CM information | Yes | Yes |
| Best approach | Use Nike’s chart | Use adidas’ chart |
This is why you should avoid copying a Nike conversion directly into an adidas product listing.
The numerical size relationship may look similar in some ranges, but the safest choice comes from the manufacturer’s own measurement system.
Are Men’s Sneakers Wider Than Women’s?
They can be, but gender alone is not enough to determine width.
Width depends on the brand, model and available width options.
For example, Nike currently provides regular, wide and extra-wide options in its footwear sizing information.
So instead of assuming:
Men’s = wide
use:
Check the actual width option
This is particularly important if you have a wide forefoot or usually buy wide shoes.
Can Women With Wide Feet Wear Men’s Sneakers?
Yes.
A men’s sneaker may be a useful alternative when a women’s version feels too narrow or when the men’s version offers a more suitable width.
But don’t automatically choose a men’s shoe just because you have wide feet.
Check:
- Toe-box width
- Available width options
- Midfoot pressure
- Heel security
- Upper material
- Actual foot measurement
A properly sized women’s wide shoe may be a better fit than an incorrectly sized men’s shoe.
What If You Have Narrow Feet?
Men’s or unisex sneakers can still work for narrow feet, but pay close attention to the heel and midfoot.
Look for:
- Secure heel hold
- Adjustable lacing
- Suitable width
- Minimal heel movement
- No excessive pressure from tightening the laces
Do not solve a loose fit by automatically choosing a smaller length.
A smaller shoe can create unnecessary pressure at the toes.
How to Check the Fit Before Wearing the Shoes Outside
When buying online, try the shoes indoors first if the retailer’s return policy permits it.
Check your toes
Your toes should not be pressed against the front of the shoe.
Check the sides
Your foot should not feel squeezed by the upper.
Check the heel
Walk normally and see whether your heel moves excessively.
Check the midfoot
The lacing should secure the foot without creating painful pressure.
Check both feet
Your two feet may differ slightly in length.
If the shoe is clearly uncomfortable during an indoor fitting, don’t assume that wearing it longer will automatically solve the problem.
Pass the 30-Second Fit Check
Check that your longest toe has comfortable space at the front.
Check whether the upper puts pressure on your forefoot or toes.
Walk indoors and check that your heel stays comfortably secure.
Can Women Wear Men’s Running Shoes?
Yes.
A woman can wear a men’s running shoe if the size, width and overall fit are appropriate.
For running, pay more attention to fit than you would for casual sneakers because you will be taking repeated steps and may spend much longer in the shoe.
Check:
- Foot length
- Width
- Heel security
- Toe clearance
- Intended running surface
- Cushioning and stability features
- Manufacturer sizing guidance
Do not assume that a men’s running shoe is automatically too firm or too wide for a woman. Evaluate the actual model.
Can Women Wear Men’s Walking and Training Shoes?
Yes.
The same sizing principle applies to walking and training shoes.
For walking shoes, focus on:
- Comfortable length
- Toe-box space
- Width
- Heel security
For training shoes, also consider:
- Lateral stability
- Secure upper
- Intended workout type
- Sole design
The important question is not whether the label says men’s or women’s.
It is whether the shoe is suitable for your foot and intended activity.

This separation helps avoid overlapping the same primary search intent across both pages.
What About UK and EU Sizes?
Do not apply the US 1.5 rule directly to UK or EU sizes.
Instead, use the brand’s chart.
Nike’s current footwear chart provides US, UK, EU, CM/JP and foot-length information, while adidas provides US, UK, EU, JP and heel-to-toe measurements.
If you need a broader international conversion, use the US, UK and EU shoe size conversion guide.
That keeps this page focused on its main topic instead of duplicating your international conversion article.
Common Unisex Shoe Sizing Mistakes
Assuming every unisex shoe is men’s-based
Not necessarily.
Check the manufacturer’s product chart.
Using the 1.5 rule for every brand
The 1.5 conversion is useful for many US athletic shoes, but it should not override the manufacturer’s chart.
Ignoring foot length
Your usual size may not work in a different brand or model.
Treating CM as universal
The CM number shown on a shoe label may not equal your measured foot length. Nike explicitly notes this distinction.
Ignoring width
Length can be correct while the shoe remains too narrow or too wide.
Measuring only one foot
Measure both feet and use the longer measurement when following a chart that recommends it.
Assuming EU sizes fit identically across brands
Different manufacturers can associate different physical measurements with the same EU number.
Choosing a smaller shoe to fix heel movement
A smaller size can create toe pressure. Check the shoe’s width and shape before changing length.
Unisex Shoe Size Chart: Common Questions
What size is a women’s 8 in men’s sneakers?
A US Women’s 8 commonly corresponds to approximately a US Men’s 6.5 under the common 1.5-size conversion.
What size is a women’s 8.5 in men’s sneakers?
A US Women’s 8.5 commonly corresponds to approximately a US Men’s 7 on a men’s-based conversion such as Nike’s current unisex chart.
What size is a women’s 9 in men’s sneakers?
A US Women’s 9 commonly corresponds to approximately a US Men’s 7.5 under the common conversion.
What size is a women’s 10 in men’s sneakers?
A US Women’s 10 commonly corresponds to approximately a US Men’s 8.5 under the common conversion.
Are unisex shoes in men’s sizes?
Some are, but not all. Check the product’s official chart to see whether the sizing is men’s-based, women’s-based or another system.
Are men’s sneakers wider than women’s?
They can be, but there is no universal width rule based only on gender. Check the actual model and available width options.
Can women with wide feet wear men’s sneakers?
Yes. A men’s sneaker may work well for some wider feet, but compare the actual shoe width and shape rather than relying only on the men’s label.
Does the 1.5 rule apply to UK shoe sizes?
No. The common 1.5 conversion discussed in this article is a US-size reference. Use the manufacturer’s UK chart for UK sizing.
Is CM sizing more accurate?
Foot-length measurement can be very useful, but do not assume the CM value printed on every shoe is identical to your measured foot length. Nike explicitly distinguishes its CM label value from foot length.
Can men wear women’s sneakers?
Yes. The same principles apply: compare length, width, shape, heel security and the manufacturer’s size chart.
Final Takeaway
Women can wear men’s sneakers, and the same is true in reverse.
The easiest starting point for many US athletic shoes is:
Women’s US size – 1.5 = Men’s US size
But the better buying process is:
Convert → Measure → Check Width → Check Brand Chart → Check Fit
Nike’s current sizing information supports the common men’s/women’s conversion relationship in its men’s-based unisex chart, while its sizing system also demonstrates why width and foot measurement matter.
adidas likewise publishes its own men’s and women’s footwear measurements, which is why brand-specific information should take priority over a generic conversion formula.
If you are buying a men’s or unisex sneaker online, don’t choose based on the gender label alone.
Choose the size and shape that fit your actual feet.
