Planning a run with a few friends that climbs 10,000' over 36 miles of paved road, and trying to decide what shoe would be the best bet. Even at a steady pace, it will probably be over 6 hours of running. My first thought was the Saucony Endorphin Speed, since it is light, cushy and responsive. I have run a marathon in the Endorphin Speed, and am happy with how it felt. Or would it be better to use a maximally cushioned shoe like a Hoka Bondi? Generally I lean toward the more firm shoes for shorter distances, like Adidas Adizero Boston or Brooks Ravenna.
