I wore this boot in Iraq for close to two years. I bought it because they were the most comfortable boot I tried on. This boot has a very cushiony insole. I really never had any bad foot odors at all. These boots were never water saturated. Repelled really gunky gooey mud very well. I wore this boot daily through top temperatures of 120-140 degrees and when it was chilly also. Sand never got in the boot. I walked on large rocks and bad surfaces and the boot held up great. It is a tool that I have to use. I bought another pair and I am wearing them now in Afghanistan. I normally wear a 10 1/2 shoe but I need at least an 11 boot. 10 1/2 is too snug. Trust me a 1/2 size larger than your shoe size.
