So happy the dynamo is back! I love the free version of these. Super flexible, lightweight, and the fabric is perfect and breathable for warmer weather and sweaty feet. This shoe has always been my daughter‘s favorite! I feel like this version runs a little more true to size compared to the last version of the dynamo, which ran small in my opinion. My daughter was in an 11 C in the past version and wears a 10.5 C in this version.
