Hello. This year I bought a pair of Nike 2k11s from NikeID after trying some in a store. This was my first pair(s) of tennis-specific shoes. Previously I wore Asics cross trainers for tennis as I wasn't playing often. Now that I've stepped up my tennis playing, I bought the 2k11s. After only two months, I've worn the top half of the forefoot sole and the toe cap so it's smooth. I play only on well maintained hardcourt surfaces so I selected the hardcourt sole in NikeID. I've played ~6 hours of singles and doubles tennis per week over the last 8 weeks or so. Since I haven't worn tennis-specific shoes before, I'm wondering if this is normal/expected? Are the 2k11s notoriously softer than other tennis shoes? Are all tennis shoes this (non)durable? Could the NikeID sole colour choice have an effect on durability? Thanks in advance for any advice/information.
