The Asics Gel Progressive Indoor shoe delivers the premium level of features making it quick, light, grippy but well supported for indoor courts. A shoe packed full of technology with great levels of stability, comfort and shock absorption. Air Mesh, synthetic leather and Personal Heel Fit in the upper provide excellent comfort and breathability. Biomorphic Fit technology allows the upper of the shoe to move in harmony with the foot, giving more comfort while in motion. This fit means the shoe material does not bunch, reducing the risk of blisters or irritation. The Impact Guidance System (IGS) is an ASICS design philosophy. It aims to make shoe components from rear to midfoot and forefoot to work together effectively to allow the body to perform in a natural manner. ASICS designers strive to compliment, not correct, how the legs and feet move. Utilises the Space Trusstic, an advanced system that creates a pocket between the Trusstic System device and the midsole, allowing for greater midsole deformation and more efficient foot function. Forefoot GEL reduces the loading forces as the foot moves into propulsion, improving performance and minimising the risk of injury.There is a vented sole and midsole which minimises weight and maximises breathability. There is also Forefoot Guidance Line, a vertical flex groove in the forefoot of the sole which encourages a more efficient running style. With a wet grip rubber outsole designed from a special blend of components they deliver excellent traction even on a wet surface. The AHAR+ (Asics High Abrasion Rubber) is an extremely tough material placed in critical areas of the shoe to offer exceptional durability. This plus version is lighter than the standard version of AHAR. Durable circular points of AHAR rubber on the sole provides brilliant grip during rotation.
