INOV-8 :

TRAILFLY™ ULTRA G 300 MAX

Launched in March 2021, the TRAILFLY™ ULTRA G 300 MAX is designed for Ultra distance trail runners wanting a generously cushioned, yet agile shoe that allows the foot to adapt and react to un-even terrain.

Over two years in the making, the development encountered many twists and turns along the way. With every iteration there was something new to learn and something new to improve, through this process we kept pushing the boundaries. With over 40 athletes testing the product totalling 18000+ kilometres, plus the addition of three patent-pending innovations, the end result is an ultra running shoe truly unique to the market place and something the team at Inov-8 are all immensely proud of.

The outsole is defined in part by the design of the midsole. For example, the 4mm deep Graphene-Grip™ cleats are orientated around the longitudinal grooves and the rubber is split between the forefoot and heel to accommodate the ADAPTER-FLEX groove. We meticulously shaped and positioned all the multi-directional cleats (there are 35 on each shoe) to improve both propulsion at the front and braking at the rear.

Through inov-8's patent-pending ADAPTER-FLEX technology, the midsole is designed to move symbiotically with the foot’s mid-tarsal joint, by decoupling the heel from the forefoot, thus promoting increased mobility and adaptability over uneven terrain. This is combined with longitudinal grooves in the forefoot, which work in tandem with the foot’s metatarsals. They allow the toes to move more independently, aiding grip and a close-to-the-ground feel.
