Sturdy enough and works as advertised, The straps were not large enough for my Sundolphin Excursion 12 ss so I purchased others that fit better not a problem. On the road, in the shower, walking several kilometres, on a sandy beach - another pair of these versatile sandals supported my plantar fasciitis-prone feet well. In fact, because of that, I gave them to him and he loves them too. This is the first pair of sketchers non slip shoes I am truly happy with. These wheels are great fun, and do make you feel great when youre out there on the skate rink with everyone else. Ordinato 46/47 ma non corrisponde, avendo un altro paio di crocs si vede bene la differenza. He truly wears them out. I expected the best sound from the Foam ones but for me I hear perfect sound from the middle sized Rubber tips. Weve not washed these yet, not sure how that would work. These are the real thing.
