Joma Rodio 22 Trainers are quality-tested by professional athletes. Designed for lighter runners and for 1-7 day training. They have been made from breathable mesh with a Jacquard finish and heat-sealed synthetic pieces, for resistance, fit and lightness. Manufactured with Joma SPORTECH seam-eliminating technology. The small perforations have been made with the VTS ventilation system that favours the transpiration and the entrance and exit of air and sweat-wicking. The insole is made of natural EVA and the insole is made of 2 mm natural EVA sewn to the cut. The midsole is made of durable one-piece phylon, sectioned to facilitate adaptation to the terrain. The DURABILITY rubber outsole boasts DIN-90 abrasion wear resistance. They also have the FLEXO system of flexible lines to provide a more natural movement of the feet.
