ASICS’ new Blazing Fast is a replacement for the Pirhana SP. Like its predecessor, it’s very light, only 4.4 ounces in a men’s size 11. The upper is a thin minimesh supported by a welded film midfoot cage and synthetic suede overlays at the heel. The toe support is an extension of the sueded tongue.
The midsole is a low-profile, molded layer of Solyte foam that’s flexible and responsive, with a measure of cushioned protection. The outersole is formed in three zones: lateral forefoot and medial heel of toughened Solyte, lateral heel arcing to the medial toe of carbon rubber, and a section of DS polyester/polyurethane centered under the metatarsals to provide increased traction and cushioning. The result is a feather-light racer that works equally well for the track or faster road races.
