Theres a good arch support for my somewhat-flat feet. I am shocked by this brand. It takes some effort to get the phone in but once after that it holds the phone pretty well. Just odd to me that one was SO small and the other was large. I have small ears and standard earplugs hurt and are always too big. Good quality shoes. What rocks about these over the adult Keens (besides the price) is that you have separate adjustment at the ankle and thats what I needed since my ankles swell sometimes and yet sometimes I have problems with my pinky toes and need things looser there. I got this for my hubby who works in negative degree weather every day. this is my first Iphone. but not too big.
