Great light weight boot. I work in law enforcement and was looking for an 8in boot with athletic feel. I run, turn and jump in these with ease. great grip. Just had a painful breaking in period with the heel. I just bought some moleskin and better socks. problem solved. I don't think they should worth over $100. I expect the lifespan (with constant field use)  to be between 6-8 months due to the materials. I would buy again but I will wait for a good sale
