The ASICS Novablast 5 is a lightweight, cushioned running shoe featuring the FF Blast Max midsole for a soft, responsive ride. Its engineered jacquard mesh upper ensures breathability and a secure fit. This is a great running training shoe, however for race day, the sled pushes and pulls demand excellent grip and the Novablast 5's outsole may lack sufficient traction. Therefore, keep this shoe as an excellent 5-20k training shoe.
