The men's model Joma R.FENIX 2209 is made in a seamless design, thanks to which the shoes adapt perfectly to the feet. The inner insole is made of preformed EVA foam. The midsole consists of a Full Dual Pulsor system - the material inside absorbs impacts and increases performance thanks to the rapidly regenerating shape. With each step, the shoes return the runner's energy, reduce the runner's effort and helps reduce fatigue after races or strength training. The sole is made of highly sturdy Durability rubber with high abrasion resistance.
