This Nike trainer was specifically engineered to accommodate a woman’s foot during fitness classes, cardio sessions, and short-distance running. The word “Air” in the name of the shoe refers to the Air Max midsole unit. It is a transparent, air-filled compound in the heel that is meant to absorb shock and deliver lightweight cushioning.
The outsole pattern in the Nike Air Bella TR features multi-directional flex grooves all throughout the unit. Most of them are concentrated in the forefoot section to make the platform pliable enough for all kinds of foot movements.
Rubber pods are placed in the key areas of the outsole. Made of a durable material, they protect the high-wear areas from abrasion. The pods also feature a more articulated tread pattern for added traction on gym surfaces.
The Air Bella TR uses a full-length EVA foam compound for cushioning. It is designed to be responsive and flexible to deliver a bouncy effect and help the foot move and bend smoothly.
The brand’s acclaimed “Air Max” technology is embedded in the heel section. It is a dense air-filled vacuum that is crafted to absorb repetitive shock during high-impact exercises. Compared to foam and other midsole materials, its advantage lies in the lightweight nature of the materials and construction. This technology has also made its way into the 2nd iteration of the Air Bella.
The major portion of the upper is comprised of a tightly-woven mesh material. It is meant to hug the foot in a supportive way without hindering movements and flexibility.
Wide synthetic overlays are added on the lateral and medial sides of the shoe. Intertwined with the lacing system, they lock the foot down when the laces are tightened.
Another overlay wraps the rearfoot. It contributes to heel stability and support, preventing wobbling and unexpected shoe removal.
The trainer sports a low-cut design. It allows for unrestricted ankle mobility during agile workout sessions.
