If you dont mind the slight slipping on the back theyre very well made and comfortable. More so, I am very, very, EXTREMELY harsh in judgement when it comes to product being marked up with no reason or benefit for the client. I am very happy with my purchase! Her other shoes start to show wear with in the first day but shes been wearing these shoes for a couple of months with no scuffs or wearing. I am always looking for the latest and greatest . They dont slip off my feet like some mule slippers. They are badly finished - the upper/material is poorly finished and lumpy where it joins the bar and there is no avoiding the rubbing and the blisters. I havent tried connecting to my PC just yet but hoping it works. aber ich möchte gerne in l haben ,ich habe schon den Verkäufer geschrieben keine Antwort bis lang ,es wäre schade ,weil das produck ieine sehr gute Qualität hat Le ho testate con una corsa da 16km e 2x10mila in pista e devo dire che non ho mai avuto problemi, batteria mai scarica e mai alcun fastidio alle orecchie o dietro sulla nuca, il peso è così esiguo che ci si dimentica di averle addosso!
