Difficult installation, if I hadn?t needed it I?d have returned it. Maybe not so lucky for a guy who really needs 11s. I will say that while it does a good job at cutting the hairs short enough where you pretty much cant see them, it wont feel like freshly shaved skin. No wonder they are so tight. They were still too narrow for my feet, my whole foot could not even fit on the sandal, they hung off of the edge, giving it a very sloppy look overall. This concerns me because they?re basically saying that the straps that are on the VR might break. It is very sturdy and holds the rear wheel off of the ground which makes it easier to work on. Unlike other slippers, the length is also spot-on and true-to-size. What the arch supports do for my feet is fill in the space to make it more comfortable for me to walk in all day. No more worries about killing my Pods accidentally in my dishwater.
