Treads are still great, still good protection from the top. These are not what was advertised. I normally wear a size 12(2e) and after reading several reviews couldn?t decide whether to go a size bigger or smaller. I have never seen the kind of visible results that I have seen since starting to use this serum. Not that big of deal except for the fact it makes a very audible "squeak" that your friends can hear as well. Sad thing is I do not wear them as much because the colour sole is white ha,ha, purely a preference thing on my part, they are very comfy and as I was standing all day for my job they were the business, I do recommend if you are standing all day. Second, the shape of the pen shaft (smooth, with a shape that is flat on each side and an elliptical curve on each side with just the slightest hint of metallic "grip") is quite comfortable and allows for perhaps a greater degree of control when performing different tasks. Pero sigue siendo insuficiente e inadecuado para un un entrenamiento competitivo en piscina; una total decepción. By the way there was nothing to download or adjust on my computer. 5 For the record after trying them on I could easily go with size 10 .
