The shaft is too narrow to be able to walk in them, mainly because the calf is lower than the design allows. The headband is a little bit stiff and while it certainly fits my head, having a little more flexibility in the headband would be ideal to give it a more perfect and comfortable fit. My daughter had already tried on the socks so we are not able to return. Sono molto felice con loro. Doesnt work at all, dont waste your money. My phone and controls work perfectly fine with my other earbuds. These iems come with three nozel inserts, bright (slightly geared toward higher frequencies), neutral (balanced), warm (slightly geared toward lower frequencies). No instructions but Installation isnt complicated at all. However, the large doesnt fit as tightly as I thought it would. I’m not really a slipper guy, I have the same old M&S pair from about 1989.
