The PT-1000 is an ultra-durable yet lightweight road & trail running shoe. UK Gears proprietary Impact Protection materials and Advanced BioFlex Technology delivers you a smooth ride and more miles for your money. The proprietary technology built into the PT-1000 took over 8 years to develop with the Army Physical Training Corps, culminating in 40 of these physically demanding instructors running thousands of miles in final prototypes. This, combined with an extensive durability test programme at SATRA laboratories, means that UK Gear can confidently claim to have developed the worlds first running shoe built to survive 1,000 miles. The PT-1000 is a 1,000 mile ultra-durable road and trail running shoe that makes no compromise on biomechanical performance or comfort. The shoe features UK Gears Force Dynamic System (FDS) -- classified technology built on a foundation of proprietary compounds and materials. This Neutral Cushioning (NC) option gives maximum shock absorption in an extremely durable and flexible package. Designed for the neutral, efficient runner who doesnt require extra stability.
