I bought these for the Nomex feature after reading that these boots are fire resistant. I guess that means its just the fabric part of the boot but here in Iraq, I need all the protection I can get. Overall they are nice boots. I'm very satisfied with the comfort and the durability. They are ideal for hot weather because they are unlined so it's just a light layer of fabric over your sock which is definitely a must in 110+ degree heat.I've had these for three months and I've had no problems. They do what they were designed to do and they seem to hold up well. If they survive my deployment out here, I'll definitely be buying another pair.
