I took pic of old slippers u can see that the bottoms held up well. Bummed these didnt work out as Ive had other Crocs sandals and they were so comfy! I really wish they would have fit. Wasnt really expecting much, especially for the price I paid back then, but thought they were worth a shot. I dont mess around with shoes. Called support and was told theyd send a replacement. Totally amazing ssooo comfy and soft , haven?t taken them off yet and even went shopping in themLove them Fit just right and its pretty too :-) The first time I set up the mount the bottom wheel rested on the cinder block base wall of the garage so I raised the mount a bit and it clear easily. Even if I have to wear them for two hours, my ears dont hurt or get sweaty.
