Buying adult shoes online can be daunting since you don’t get to try the shoes on first. Here are a few tips to help you get your correct size when shopping for the best walking shoes for adults: Familiarize yourself with international size conversions. A U.S. size six for women translates to a size 36 for EU sizes, 3.5 for U.K. sizes, and 22.5 for Japanese sizes. Look for shops that offer free shipping, free returns, and free exchanges like KURU. This way, you can return or exchange your shoes for the right size if they don’t fit you. Measure your feet using a Brannock device the next time you shop in a brick and mortar store so you can be better sure of your size.
