How To Measure Your Shoe Size
Here are the best shoe size conversion charts - in US, UK, European, and inches, for men's, kid's and women's shoes.
If you've ever wondered "What size shoe is a 38?" (It is a men's size 7.5 in the US) or "What is a size 40 in shoes?" (that'd be a US men's size 9.5), read on to learn how to measure shoe sizes in different countries.
How do you measure shoe size? It is possible to measure your own foot using a ruler or a Brannock device, but since our feet our three dimensional, this will only approximate your measurements. After you've measured your foot, try using our conversion charts below to see what your size is. Be mindful that different brands, like Altra running shoes vs. Brooks running shoes vs. Oboz hiking boots, maybe run slightly different in sizes.

FAQ & Tips
- What if I am between shoe sizes? We recommend you should size up, especially in active & sports shoes. This includes running shoes and hiking boots.
- Does 0.5 size make a difference in shoes? Yes, it certainly does! Wearing shoes that are too small can cause pain and injuries. Blisters, loss of toenails and bunions can all result from wearing shoes that are even 0.5 size too small. These are common ailments of beginner runners.
- Is one foot bigger than the other? It is common for people to have one foot that is slightly bigger than the other. Our tip is that you should buy shoes that fit the larger foot (buy pairs of shoes in the larger size of the two).
- Should shoes be tight or loose? Unfortunately, this is not a simple question. Shoes should not be too tight or too loose. You should be able to put a thumbs width at the end of your toe box, between your big toe and the pointy end of the shoe. You should also be able to snuggly fit your index finger between your heel and the back of the shoe. If you have not much (or not enough!) space in either of these areas, try a different size shoe.
- When should I try on shoes? A great tip for runners is to try on running shoes at the end of a work day. As you run, just like when you are on your feet for work, your feet swell. You will want to try on running shoes when your feet are at their largest. This allows them to still fit comfortably after a long distance run.
- What size shoe should I buy? This shoe chart is not a guarantee your shoes will fit. If you are in the area of Memphis, Tennessee, run on in to one of our running specialty & gear stores and our experienced fit experts will help you out!
Image below: A Brannock device is one tool run specialists use to measure shoe size. It can measure not only foot length, but also foot width.
