I've had the Fox Launch pads for about 7 months now and I don't have a single complaint. There comfortable on and off the bike, there not too hot, but provide plenty of protection and they stay in place. The "X-Up" strap system in the back really does help. Go with them and you won't be disapointed
The best (but probably one of the most expensive) setup ive found is running the fox radius soft knee pad (about $30) under the Launch knee/shin pads. This combination provides a lot of protection, keeps the knee/shin pads totally stationary, and prevents any chaffing or rashes caused by the knee/shin pads
The Fox Launch's: I've heard complaint of the x-up buckle coming undone during impact...when you need that firmly in place....I hear they are very comfy and don't move around too. But if a pad doesn't protect, its useless.
TLD's Combats - my favorites so far. They just stay in place on my legs. The five straps help keep the secure during pedaling and falling. This past season I wore knee warmers over the top of them and nothing moved that set-up.
yeah the foxs are awesome i like the x-up buckle upy style of straps and they dont chafe at all i also like that you can walk around with them on with out the knee gaurd jabbing you in the low thigh too bad.
