I've been wearing Asics Gel-Kayano for decades and decided to give them a try. Wow! They were noticeably smoother and the motion control I needed was exceptional too. He has a redesigned truss, perhaps this change has increased comfort. However, I haven't tried the latest version of the Kayano (20) so I'm not sure if the level of comfort in this shoe is comparable, but I'm very happy with this new shoe!
Pros
Rearfoot and Forefoot GEL Cushioning System - cushions impact during impact and liftoff, allowing for multi-plane motion as the foot progresses through the gait cycle.
Model 10 is completely different from previous versions of GT 2000, ASICS made a mistake in this change. If you like the previous version, don't buy this one. I rode this pair 30 miles and will not run in them again. piss off!
Pros
FLYTEFOAM Propel Technology is an energizing foam formula from ASICS that offers excellent bounce thanks to its unique elastomeric composition.
I wear them most of the time, but after some mistakes with too narrow toes in GT-2000 4, 5, 6 model, this model continues the trend of improvement with no real flaws. I find that the heel doesn't feel as deep as the 7 (I skipped 8 and 9), but I also have thick orthotics. In any case, this was not a performance issue.
