I can stand for hours in them without my feet hurting. Besides the slightly washed out colours and somewhat hard side mouse buttons, I love EVERYTHING about this mouse and it will definitely be my choice for quite a while. Cosa non mi è piaciuto: nulla da segnalare. Haha I guess thats a good problem to have! The panels are pretty nice, but obvious particle board. Within a week the front is stretching out to a more comfortable fit. All in all, Recommended. Really disappointed at the construction and the inability to communicate with anyone about a return/replacement. They fit perfectly! These make my feet feel as good as my expensive tennis shoes.
