I wear a woman's size 10 or 11 (depending on the maker) and the size 11 just fits my foot with toes touching. I have a large bunion on one foot and have bought only men's sneakers for years because of painful narrow shoes for women...even the ones that say WW for extra wide. These shoes are snug in length and in width but they don't hurt my feet from the pressure so the fabric must have some nice 'give' to it. I did have to replace the inner sole immediately because it offered no padding at all. I have had so many comments about these shoes from strangers! I find them colorful and fun and just bought some more in a different pattern and ordered a size 12 so I think it will fit well, even with a better insole.
The size runs a bit small. The shoe fits snug in length and width (I have a very wide forefoot). Despite being snug, they are not painful. That is unusual for my tender bunions. The colors are pretty but not nearly as vibrant as on the web photo. I wish the inside bottoms had a little more padding. Overall, these are a pair I will wear and enjoy their unique design.
