I love my crocs and wear them during the warm months of the year.
They are also not good in the rain.
I wear socks with them and give them a good soapy wash frequently. Never had any smell issues.
They are great for traveling. They pack well and are easy going through security.
Last year in Aruba I was pulled aside for secondary screening and they took my crocs to dust for explosives. I thought that was odd. I would never think of putting explosives in a pair of holey shoes lol.
I don’t. In the rain, snow, or deep enough puddle, my feet may get wet so walking may chaff a bit, but the advantage is how quickly both my feet and the Crocs dry
