Soft Top DuoMax

Soft Top Duomax is a softer top layer of the Duomax midsole. Together with the Gender Specific Space Trusstic, Soft Top Duomax accommodates for fluctuations in women's hormonal levels which cause the foot arches to be lowered, creating more pressure on the plantar fascia. By using a lower-density material, Soft Top Duomax provides a more comfortable transition from heel strike to toe-off without sacrificing stability.

Gender Specific Forefoot Cushioning

Gender Specific Forefoot Cushioning refers to the inclusion of specially formulated Solyte material in the forefoot. The material's density is reduced, allowing the female foot to compress it sufficiently and benefit fully from the bounce-back qualities of Solyte. Traditionally, women's running shoes contained cushioning material of the same density as men's. However, as women are usually lighter than men, the female foot would not fully compress the material, resulting in a less than optimal ride. Gender Specific Forefoot Cushioning addresses this issue and provides women with a more comfortable and responsive ride. The cushioning material, located under the ball of the foot and extending across the width of the shoe, also acts as an efficient shock absorber.

AHAR+

ASICS High Abrasion Resistance Rubber (AHAR) is a tough compound used at the heavy contact area of the outsole, for example the heel. It helps to reduce excessive wear. AHAR+ is a lighter version of AHAR.
