I wanted to love these shoes so much I read all the advertising loved the design and the look/feel , but to be honest the stack height seemed too high and unstable, poor ventilation and my feet got really hot in it, and next to my Hoka Bondi 7, Hoka Shift killed so much in every way I returned my Saucony and shopped in another pair of Bondi. If you really want a Saucony go for the Speed, otherwise check it out and try the Hoka, I tell you you'll love it!
