In the first photo, a size 15 EEE foot, next to a size 15 product, next to a size 15 shoe from a well-known brand. The Voxge Sock sneaker looks a little tight, but is flexible enough and forgiving to fit mine Gorilla hugs leg very comfortably as seen in second picture. In the third photo, I show my thick-skinned flexibility for a side view. I absolutely love everything about it. I store my water shoes for gym workouts. It's the perfect sockless shoe for getting back and forth. Also exceptional quality.
