Ive worn Sketchers for years and own several different styles. Really really wanted to love these but they are just too heavy and rub blisters on the tops of my feet. Evidently she really likes them because Ive heard that she now wears them every day. The only thing I was NOT HAPPY about was the fact that there was NO INSTRUCTIONS. Will see if they fit better after breaking in. I would suggest ordering a size or two bigger than you wear. This set is perfect. The biggest issue I have is the uncomfortable earcups. Comparison to HTC Vive: HTC Vive has superior spatial tracking, and frankly is probably the highest quality experience in VR today. I would think all Crocs would fit the same as long as the size was the same.
