Alass, after 5 years my old boots are completely worn out and have to be replaced. I want to go with something that will give MAXIMUM protection. I was thinking Alpinestars Tech 8's or SIDI Force???

A kid who was riding with us once, came off the pegs while landing a huge jump (didn't have nerf bars!). He ran over his leg, while wearing Tech 8's. Luckily the bike (Blaster) and he were both light, and he walked away without a scratch!
