The GT-2000™ 15 brings the fun back to stability running. We loaded it with a softer, plusher FF BLAST™ MAX cushioning because more bounce is always better. Every step feels like a trampoline—soft when you land, explosive when you push off.Featuring a reimagined FF BLAST™ MAX midsole with a softer formulation and an extra 2mm of foam than the previous model, every landing feels cloud-like while toe-off delivers a powerful, springy response. Meanwhile, the 3D GUIDANCE SYSTEM™ provides intelligent, adaptive support that activates exactly when you need it, keeping your stride smooth and balanced without feeling restrictive.Total CO₂ emission per pair of the shoes are 10.4 kg CO₂e **Assessed using ASICS' carbon footprint methodology version 1.3.
