The base of the wrist rest is also firm providing stability in transport but largely insignificant in normal use. Being my daily drivers I dont want to do this each time. I even got complimented on these shoes by a man! The wireless USB stick fits inside the case for transportation or when not in use, so you can?t easily lose it. It has nice sound and features. *-edit 9-29-18Theyve added a record-a-key feature, and Ive already used it! If I could give these zero stars and the company I would. I live in crocs and had a whole batch of classic crocs sized W2M4 (not an offered size now. Im still wearing those for around the house, driving, yard work, even mowing lawn. So basically this thing, as a premium product, is originally not supported by their own software!
