The Olympus 3.0 towers above the other models on this list—literally. In contrast to the Superior, the Olympus provides 33 mm of cushioning, more than any other shoe on this list. It’s a level of cushioning, in combination with a lugged sole, that’s ready to meet the challenge of hundred-mile ultramarathons over rugged mountain trails. Or for the rest of us, enough cushioning to be fantastically comfortable, no matter where we run.
