I bought this strictly for wearing while refereeing water polo.  The soles seem to be pretty non-slip on a wet pool-deck, which is great, and they are comfortable right out of the box.  I don't know how long they will hold up, but since I won't be running in them, I would expect them to last a while, anyway.  They aren't going to replace my Brooks Beast shoes (I use those for refereeing soccer), but then they are also about 1/3 the price!
