This is by far the best tactical boot I have ever worn in my 26 year career. It is light and durable. The tread is solid, no slip and no slide in the mud. My foot is not all wet when I take my boots off, a real challenge here in South Texas. It has a neat feature on the 5.0 the tounge has a velcro compartment to hide your shoe strings to maintain the professional appearance. It had a break-in time of two days and now its like putting on my ranch boots. I highly reccomend this boot to everyone.
