The title says it all. Great shoe! The medium is quite wide and comfy, the sole is flexible, great design; we have it in white-multi - goes with almost everything. My girl is 9.5 months old and wears size 3.5M, but she is on the small side. The only drawback is that it's easy for the baby to open the strap by pulling the flower on top; it's actually a game for her - mommy secures the strap - baby undoes the strap - and repeat. I loved it so much, i just got bigger size in the brown. Now i'm waiting for summer sandals from StrideRite with the same flexible sole.
