These are definitely not leather so sellers please update the description. The shoes were ordered half a size bigger. It is a little tricky to rewind since it is three taps. Merciii Amazon cest super je ladore ,elle est magnifique, jolie, confortable 5étoiles youpi 🖐❤🖐❤🖐 Id never actually used Zwift before, but I new Id need that type of feedback to keep from getting extremely bored with the whole idea of riding indoors. Ill have to buy a different pair because I cant wear these. Actually, better than expected because Birkenstock shoes usually look wide and loose when people walk in them. I use them everyday When they arrived they looked great, so I made some jewellery and wore a ring I made. Not bad or good just optical.
