Volume is great. - The mousefeet are super fast which I love, but as other reviewers have pointed out, they are definitely on the loud side, not scratchy, but definitely rough. For those people that like to see pics and look at reviews prior to purchasing, I will provide pics showing the shoe, the shoe on my foot and the shoe on with me standing (to see how wide they stretch) to hopefully give you an idea of what youll be working with. Really seems that not a lot of refinement has gone into the product. It fit as sized. Ils sont un peu lourd et dépassent des oreilles. never seen it before on shoes. Naturally, I have a hard time finding soaps that dont irritate my skin. Sturdy looks but expensive It is quite heavy, as the bottom is made with some heavy duty thick rubber, this is great for durability, as it seems it will last a while.
