If you want it to stand a bike up, this is ok, maybe even small work on bike and cleaning, but nothing complex as this will fall over and scratch your bike. Fits are all the same size. My main issue is that I have abnormally large ears. I just ordered the two individual, separate L/R Quest, mono earbuds as they got amazing reviews. We are able to fit ALL four of our bikes neatly in the garage so they are not all dumped in each other. Now they say they are a 39 so I guess you could say that they are a 6 rather than a 5. These are perfect, no pain when I walk or afterwards. If you got that from in-ear phones, you would be surely destroying your hearing (as you probably are when you bask in that thumping bass at the club). These are nice slippers, comfortable, cute, keep my feet warm and clean in my Michigan house with no carpet/rugs. Although theyre labeled as a "D" width (a size I normally wear), I found this pair to be too binding, particularly in the forward part of my foot.
