Propper's 8" Series 100 military boots deliver support and durability. Made from durable 1,000 denier nylon and water-resistant suede, these boots are able to withstand constant use and still retain their shape, while the arch is fast-rope compatible to reduce abrasions caused by ladders or ropes. For ease of use, the speed lace system allows you to get the boots on and off quickly and ensure a snug, comfortable fit. An anti-microbial lining promotes breathability and blocks the growth of odor-causing bacteria to boost the freshness and extend the life of the boots. The removable open cell foam inserts are washable, breathable and mold to the shape of your foot for maximum arch support and weight distribution.
