The Asics Womens GEL-Quantum 180 4 Running shoes combine premium performance technologies into a comfortable and stylish design that's ideal for the gym. Featuring 180 degrees of ASICS GEL® technology for maximum cushioning, absorbing shock by dissipating impact in the areas where you need it the most. The midsole provides extra shock absorption with the N-Solyte foam, a lightweight material that provides a bouncy, springy feeling underfoot. For a more stable ride, the GEL-QUANTUM™180 4 includes the full-length trusstic support system. This reinforces the middle part of the shoe and prevents any twisting as your feet hit the ground, making for a more comfortable landing and toe-off.
