Here are my sz 12 Wimbledon-colorway Adidas B7s-- they lasted about a little under 5 months playing about 2-3 hrs per week. Fair amount of tread left on forefoot but all gone at the very front. That's an improvement on my CourtBallistecs which I wear out in less than 3 months at the toe and outer heel under the same conditions. I've had 100% of Nike claims accepted and I'm sure these will be too as the hole goes right through.
(apologies for poor quality picture)
