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, lose 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 lose? Unfortunately, this is not a simple question. Shoes should not be too tight or too lose. 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!
