So I picked up the Kayano 15s yesterday at my local Dicks Sporting Goods. Over the past year I have run in the Kayano 14s, Nike Air Structure Triax 11, Brooks Infinity, and Brooks Axiom 3. I am 6'1" 170 lb primarily I am an 800m-1000m runner. One of the updates I appreciated was the better padding around the heel counter so that the bone in my heel/ankle that sticks out doesn’t rub up against and wear the back of the shoe out to its plastic core (the Kayano 14s and Brooks Infinity did just that). These Kayanos are also a lot lighter than the 14s. They are still a very stiff shoe which is nice in the winter since the majority of my runs are on the roads now. The update also seems to have more gel and a more cushioned shoe overall. On my narrow foot it fits well and the toe box is very roomy. I would caution those with wider feet to get the wider version (duh). The only color available at this location was the poo colored accents but that is life. Asics also updated their price to 139.99. Overall a 9/10 shoe Asics did a very good job with the update.
