Rated 1 out of 5 by Durability Problem Had a couple of seasons on the LD3 that were getting worn so purchased the LD4 to start the 2014 season. Four weeks and nine races into the season the little air holes on the instep of the shoe were almost all tearing around the hole and some tears had connected to another hole. They looked like they were not too far away from coming apart so returned the shoe and purchased another brand. The LD3 did not have the holes or the problem and would have gladly purchased another pair of LD3’s but they are no longer available. Teammates with the LD4 are having the same problem. It was a great ride while it lasted but it appears the design has a fatal flaw. April 6, 2014
