Okay! For you street riders who have lusted after a pair of Security Evo boots but (1) they're too expensive, and (2) you want to be able to walk around in them, here's your boot. The Evo Sports GTX is less expensive than the Security Evo, less bulky, and more upright. The inner shell is high tech ABS plastic and since it can be made by machine, instead of by hand like the Security Evo, it costs less to produce. The outer shell can be replaced. Other features: replaceable toe sliders, reflective trim, calf adjustment, and titanium inserts at heel and calf.
