The ASICS GEL-VIRAGE 4 delivers comfort and function for any runner who requires a mild level of support. The latest edition of this shoe has an open mesh upper to increase the breathability of the trainer. A dual density midsole system has been positioned to enhance support and stability. One half is made of SpEVA that has improved bounce back characteristics for enhanced comfort and performance. GEL in the rearfoot attenuates shock during impact and allows for a smooth, easy transition through the gait cycle. The ASICS GEL-VIRAGE 4 Running Shoe also benefits from a Trusstic System, a plastic component that reduces the weight of the model sole unit while retaining the structural integrity of the shoe.
