The lightest super shoe on the market, and proud owner of not one, but two, sub 2-hour marathons. This shoe was introduced months ago and was finally put to the test. At 97 grams it beats out the nearest competitor by almost 50 grams. It's the fastest super shoe on the market.
The lightest thing anyone's still willing to call a marathon shoe — 97 grams, closer to a racing flat than a stacked super shoe, and it beats the nearest competitor by almost 50. Two sub-2 exhibitions ran in these, so the ceiling isn't in question. The catch is price and lifespan: this is a glass cannon, built to detonate over one block of racing, not to babysit your long runs. Worth it if you're chasing a number. Overkill if you're not.
