The moving the mouse causes the pad to move which is extremely annoying. For those who are serious about keeping their cars clean and tight this is worth the money, as there is a small investment to get up and running, about $15. Naturalizer should be ashamed of this product. Theyre VERY comfy, Im already wearing them about. I knew it would be slightly bigger but wearable. (Hopefully, they can fix this! This gives me more protection. The material is different - much stiffer and less flexible with a more pronounced arch - and worse yet the sizing is different. Now they are just flopping when i walk and might as well throw them away. would like the company to sent me a new pair.
