Introducing the Fuse 3.0. This model features upgraded principles of stability, fit and traction for groundbreaking performance. We have utilized a wider last for this model, and an improved PUMAGRIP rubber compound. Built with insights from our athletes and the community, the Fuse 3.0 is engineered for strength. Fuse 3.0 is highlighted by a TPU mesh upper for durability, and a newly added medial side eyestay rope guard-which provides protection for laces. Continued in this model is our FuseFlex metatarsal flex grooves, and a redesigned TPU heel clip for support, stability, and on wall guidance. We have included a drop in dual density midsole which gives you a firmer heel compound and more flexible forefoot cushioning. The Fuse 3.0 is the ultimate strength trainer, helping to stand out from the competition and take your training to the next level.
