This was a gift to myself, a special one. Paint rubbed off and biggie had no eyes. Just go get yourself a pair of dollar store headphones, itll be almost as good as these. Not that big of deal except for the fact it makes a very audible "squeak" that your friends can hear as well. The shoes will keep your feet very warm and sometimes too warm. Its impossible to say but it seems that being so soft they might wear out a lot sooner than traditional running shoes but I wont know for sure until time passes. If I cannot get any answers I will have to return it no big loss. For reference, I have a BOB revolution flex 3. Other fun things you can do with the superx earbuds is that you can connect them to the Apple TV! A side effect of the shoe arch being too high for me I shift my weight when walking and have collapsed the cork on the right rear of the right shoe.
