I still have mixed feelings. I followed the size guide and yet got toe bump. Not sure if I should get a 0.5 bigger. First two treadmill runs were fine but the third one felt my feet could use a bit more room. Not yet try running on the road

Great trainers

I found the trainers quite snug fitting even ordering a size up. The quality is brilliant and they are super comfortable when wearing them. I predominantly use them when I'm either at the gym or using the treadmill at home. With a lot of other trainers, I find my feet hurt afterwards but I haven't experienced this yet with these! Thick, cushioned sole and cushioned near the Achilles heel which is great as they don't rub and leave blisters.

I really like these trainers!

I nearly didn't make the purchase because of the negative reviews. However, I'm glad I did because for whatever reason these trainers seem to fit me perfectly. I am a size 8 and I found these true to size. I wanted trainers I can walk in that will support my feet properly and these certainly do that.

Might be great without the plastic

I was looking for a long distance training shoe and I've had great experience with past adidas shoes fit and performance but the plastic eyestays on each sides rubbed and put a lot of pressure on the top of the foot making the shoes painful on a run. They were so uncomfortable that I've had to return them after 2 runs (10 miles total). I did like the ride/cushion more than my current Hoka Cliftons and Brooks Ghosts but can't use the Ultra Boost Lights because of the lacing system, all other aspects of fit were great. I hoped they'd somehow break in and tried different lacing configurations and wearing them around the house but were simply unusable. If they'd ditch the plastic and develop a better lacing system they might be great, but seems adidas is focused on ... MoreI was looking for a long distance training shoe and I've had great experience with past adidas shoes fit and performance but the plastic eyestays on each sides rubbed and put a lot of pressure on the top of the foot making the shoes painful on a run.

Avoid these if you plan to run in them.

Not true to size

I am a big Ultraboost fan. I have always been size 5.5. These are not true to size. The sole is comfortable but the shoe itself is tight. I tried them out and after my 1st wear I was left with a sore toe. Not a great design and definitely don't feel light unlike the other Ultraboosts I have had in the past. This has put me off wearing them.

Super comfortable

Hands down the best trainers I’ve owned. Excellent quality and comfort. Easy to wipe clean and keep the feet secure and cozy! A little tight so would advise to go half a size up. Other than that 10/10 all round.

These Run So Small

Ordered these half a size larger than my usual size due to reviews of them running small but they are still far too small. Order a whole size up to your usual size! Really disappointing as they seem comfortable otherwise.
