One main reason I bought this shoe was for water shedding, which it does well, Unfortunately, they put a cushy, absorbent insole in it. After hot, humid long runs, I wring a good fluid ounce of sweat out of each insole. The weight gain and "squishiness" is noticeable. I replaced the insoles with those from my Hoka Challenger. Not perfect fit but the shoes drain like a champ now. Putting an absorbent insole in a water shedding shoe deserves an espn-esque "c'mon man!", imo. Very happy with the shoe otherwise.
