I bought these shoes in a size 8.5, which is my normal shoe size. They fit PERFECTLY as expected  I sometimes purchase a size 9 for boots just to give me a little bit more room when wearing socks, but I would say to purchase your normal sneaker size.  I already own a pair of these in a different color so I knew I loved them. And Ive owned that pair for 2 years & they are still in great condition! So I knew I wanted another pair in a different color. They are so comfortable, literally feels like you're walking on cushions!!! I have pain in my feet from planters fasciitis as well as a bunion and these  sketchers go walk shoes are like heaven for my feet!!  The package shipped quickly and secure. I absolutely recommend these to anyone who wants a comfortable walking shoe. Ive attached some pictures to show the look and quality of these shoes.
