I wish I knew the thickness before I bought it. I sized up to a 9 in these after reading other reviews; they fit perfectly length-wise, but feel a little tight in the width. It has made the sandal very squeaky and the overall look is not good as too much of my insole can be seen. I think the towel holder shelf is probably only meant for hand towels because it doesnt have sufficient space for a normal bath towel. These are sturdy headphones yet very comfortable to wear especially for working out. I even installed it myself & I am not knowledgeable on bike/tool stuff, but a bike stand was super handy. So, Id ask the company to do better physical inspections of the objects, and Id tell future customers to use gloves when grabbing it out of the box and putting it together. The way this is advertised I got a size up but its wayyyyyy too small you need at least 2-3 sizes upIts really bad that its not advertised that way so people know what to expect and Im not expecting it to be perfect but it would barely close or reach the other side to even close and now to return it Im expected to pay another $5 out of my refund which is crazy especially since Im not getting a replacement evenAlso the way this came packaged was squished into a plastic bag that I cant even fit back And the box it comes in is long and annoying to move around, so you dont want to miss that delivery! In fact the directions say to wear for a few hours a day, esp.
