I have been playing on these since summer and the soles are still in good shape. I play two times a week most of the time and they have been really nice. They feel really light and are very breathable. The soles seem to be wearing at about the same rate as the Babolat Michelin rubber soles I had before, so that is good. I usually wear through the sides before the soles go south, but these don't show any stressing there yet. I am going to order another pair today since they are on sale. I will just keep them around for when my current pair wears out. I like these THAT much. I don't see a need to invest >$100 in a shoe when I get what I want at half the price.
For the money I'm very happy with my purchase, comfortable, played well my first time, feet did't hurt, didn't need much breaking in, nice looking, fit true to size.
I like this shoe as it is extremely excellent and lightweight. Easy to carry on play and affordable.
