The Asics Novablast 4 is the latest edition of the popular running shoe, known for its versatility since its first release. This version features an updated knitted, sock-like upper for a comfortable fit, similar to the Nimbus 25. The midsole now consists of FF Blast+ ECO, made from 20% recycled bio-based content. The 8mm heel drop provides a bouncy, trampoline-inspired effect. The outsole is made with AHAR rubber, ensuring sufficient grip for road running in various weather conditions.
