Super Comfortable, Perfect Fit, True To Size
I've owned many pairs of Ultraboosts going back to the first generation. These are the first I've tried without the cage to lock my foot down. I knew this would make them more lightweight and comfortable but I was concerned this would come at the sacrifice of stabilty. Not the case at all. These feel very secure. I like having the best of both worlds.
As far as durability is concerned, that remains to he seen. The Primeknit upper, especially in the toe box is very flexible, but also much less subtantial than on prior releases of yhe Ultraboost. If they hold up as well, this is by far the best release to date

There is no heel lockdown whatsoever, lot of slip
If the heel slippage wasn’t a problem this would be the best long run shoe in the market , unfortunately the heel slip is really bad even when I size down and then it is uncomfortable. Sad , always been my favorite shoes and now I can’t wear them.
