These are so darlin' and there is no breaking in period. They are so cute I clapped my hands together after I opened them today. I put them straight on and wore them to the store and out to do other errands- no blisters, no discomfort--no problems! they're perfect! Comfy & light as all the other Croc shoe/clogs I've ever worn. They're a really cute alternative to little sneakers- these are a no-brainer & I love 'em!
