Pearl Izumi I.S.O. Transition
The draw: Quick transitions and a snappy feel
Mid-foot, forefoot and even heel strikers who desire a responsive ride and ample cushioning in their 70.3 or Ironman shoes, take note. The I.S.O. Transition, developed with feedback from Tim DeBoom, is a cross between a trainer and a minimalist race shoe. Made for sockless running, the upper includes a seamless lining that wicks moisture, which reduces chafing and hot spots. Stick to the roads when wearing these, as small rocks, debris and mud can get caught in the drainage holes.
