The Nike Air Max Bella TR 5 combines the bounce and beauty of Max Air cushioning with a flat sole that lends a stabilizing advantage while you tone and sculpt with weight. This updated design increases the containment and support around the sides and top of your foot to help keep you steady on your feet and secure during demanding strength workouts.Supportive Containment The stretchy strap integrates with the sleeve-like construction and traditional lacing for midfoot containment with a more secure and snug fit that doesn't slack when you need to push it hard. Synthetic leather wraps the heel for added durability. Steady Comfort The foam midsole and a Max Air unit in the heel bring stability and high-performance cushioning to every step. The raised edging braces your foot during side-to-side movement. Smart Traction The flat sole helps keep you stable on gym surfaces while the rubber tread gives you more grip. Textured mesh is lightweight and breathable. Stretchy strap crosses over the top of your foot for a more secure fit. Pull tabs on the tongue and heel for easy on and off.
