Everything its fine with these racks. Literally 1 day after I ordered. Beside looks they still are great sandals. These are my work "boots" lol. She says they are comfortable, and she is wearing them every day. My recommendation would be to have slits on BOTH covers and not just vertically but also an option for horizontal as well seeing as thought that?s what I needed. il vaut mieux évoluer par soi même . Update,,july16 2020,,still loving these,,bought another pair for my daughter about 2 weeks ago,cant say enough good things about this headset, well worth your money! easily adjustible. Small and light enough for easy storage and assembly.
