The GT-4000 incorporates 2 legendary support ASICS shoes into one (GT-3000 and GEL-FOUNDATION). This NEW model provides a highly stable and supportive ride with new tooling that carries SpEVA foam and FlyteFoam. The support is extended in the midfoot to provide a supportive platform through out the entirety of the gait cycle. The upper has been refined to further improve the fit and overall running experience. Utilising a more contemporary design that doesn't look too “bulkyâ the consumer now has a fresh take on a shoe in this category. Key updates include a modified fit over the forefoot (wider and higher) that provides more room and a bunion window on the medial side.
