Works well in our bathroom. There seems to be a ridge running across the arch of the foot. It is def a Good buy. i believe if you go up to a 1x or 2x in size this would still fit. Ive only been wearing these for about 8 hours since they arrived today, but I think that says quite a bit. These fit incredibly weird and are super uncomfortable. Ich habe die AHG Ultra Comfort Ohrpolster gegen die originalen Ohrpolster des HyperX Clod Alpha getauscht und habe sofort den positiven Unterschied bemerkt. I?ve used these in the backyard to play with big doggos. My three star review is based solely (pun intended) on the fact that they are the LOUDEST flip-flops I have ever owned. It?s always falling out even with the smallest of moment.
