Our approach for the GT-1000 14 TR shoe was to modernize the shoe with a more energized cushioning experience. The midsole is updated with FF BLAST cushioning. It's designed to help create cloud-like cushioning and a more energetic response. This design also features a 3D GUIDANCE SYSTEM to help increase stability for a balanced and confident stride. Lastly, the trail-specific outsole design helps create better traction, improved softness, and advanced durability for mixed terrain.
