The Bullpadel Hack Hybrid Fly 21 is the latest version of the popular Hack shoe from Bullpadel. The shoe is made specifically for padel and is therefore good for those many small fast steps around the court. The shoe is made with a lightweight and flexible outer, while the "Lycra Sock Fit" top ensures good support and stability. The sole is made for good grip in the padel court and is even equipped with the "Rotox" system, which contributes to the fast changes of direction. The shoe also comes with "TPU stabilizer" and "OrthoLite" insole to provide comfort and stability. To help with flexibility, the shoe features the "FLEX RIFT" system which ensures stable twisting of the shoe during play .
