ASICS' AHAR™ and AHARPLUS™ are outsole materials designed with excellent abrasion resistance and comfort in mind. The rubber compound utilized actually originates from care tires, so athletes can expect a high level of durability. Conversely, the superior comfort traces back to its spongy design, which is 50% lighter than what is found in traditional products. The main differences between the two iterations of this technology are as follows:

• AHAR™: 2x the abrasion resistance of conventional rubber compounds
• AHARPLUS™: 3x the abrasion resistance of conventional rubber compounds
