Shoes fit true to size. I ordered a big kids Sz 2. These shoes are amazing arch support & comfort. Theyre a normal wide-not narrow or tight on her feet. Theyre great for school PE to hiking. The material is very strong and tough on the outside with thick rubber bottoms. My 6 1/2 yr old loves these shoes! Weve so far ordered the purple & aqua. I would definitely order these again soon with the next size up for the next growth spurt!
