I had to order a smaller size as I walked right out of the first pair. great value ,very good traction on wet surfaces and the fit is exact The quality is durable as well. The exterior is adorable and solidly stitched and crafted. All I can say is that I was expecting different results; I dont think Ill send back the pajamas (they do look very cute on my wife) but I may have to have a talk with the company about their product being TOO high of quality. The Velcro is very strong so the end of the strap should never loosen off or go flapping around. This product however is a homerun for those of us who desire the unique properties of SiO2 based products. Hence the chewed up pic. Dieses Knistern und gleichzeitig schnelle Piepstöne reagieren besonders empfindlich wenn man nahe dem Fernseher steht. We had to adjust the size but that was fairly easy for my husband to saw off--but loving it
