I ordered one too many of these sandals ( and the other model by the same company ) so wanted to share useful sizing and width info. My daughter is 9 and wears generally 3.5 ( both in Puma, Plae and pediped). She has very narrow feet. These shoes her sizing is 2. Both 3 and 4 were way way too big. Width is perfect. The other style ( more popular with all leather insoles) were too wide.
