An ultralight side-zip tactical boot, the Belleville TR1040-ZWP bloodborne pathogen/waterproof boot is engineered to provide maximum support and comfort without the weight of standard duty boots. At the core is the PTO® orthotic footbed; a proprietary, load bearing removable insert that uniquely combines the benefits of shock absorbing foam with superior arch support. Combined with a shock absorbing EVA midsole and dual density nitrile rubber slip & oil resisting outsole, the TR1040-ZWP is a new benchmark for light, fast, engineered tactical boots.
