For runners who've been searching for the lightest Hoka One One running shoe on the list, here it is. The Cavu 2 is basically on the opposite end of the spectrum from the Stinson ATR 5. It's only 7.2 ounces, so it's your go-to option when competitive running is on your mind. Rather than plush cushioning, this shoe offers you ProFly cushioning, which is a responsive and rubberized foam in the midsole. The Cavu 2's structure is intended to be flexible, breathable, and overall minimalistic.
