Well this is kind of like your classic style slipper with a little bit of the insole that has some grips to it but wasnt looking for anything spectacular but apparently I ordered the wrong size they ordered a size 10 usually a size 10 and slippers or sandals or flip-flops work for me. This mouse started doing the same thing only one month after I got it! At $139 though, if sound and music is the driving force, buy these. To me, that is the big plus on this style. These are actually worn to minimize stomping around the house, it’s meant to be dragged (and allow minimal bending) on the carpet and wooden floors. Ok ladies, here is the skinny on sizing yourself for a corset. I always had an issue with wired mice and the cable getting in the way but not any more! That, to me, says he’s hooked! Sehr stabil, sehr schnell aufgebaut, komfortabel in der Bedienung. I’ll get some to match the other ones I have in place.
