I also want to say that the customer service of this company is phenomenal! With the other shoes that I returned I thought that they were so heavy it would just make him fall even more, but these are so light weight that they?re just like 2nd skin for him. Better than the Logitech Pro and any other wireless or even wired mouse out there. For perfectly, easy to install. You cannot get more Value For Money. although not neutral/for critical listening (as most senns are known for), they do provide a well balanced sound with slight emphasis on the bass (but not at exaggerated levels). The size up c9 was way too big and this c8 size was just for the day. They look great and Im very glad I picked this style and brand. Shell be able to grow into them. It?s the heal sticking to the logo on the sole.
