I need to start suggesting everyone that owns Gel-Kayano, Gel-Cumulus and/or GT-1000 14, that if for example you wear US men's size 11 with these, order 11.5 in Gel-Excite 11. When I did a search using AI for getting suggestions on the fitment and sizing of the Gel-Excite's 11, I got 'order half size up' in all results, I was a little skeptical but I follow the suggestions and I'm glad I did because no way that size 11 would've fit me, 11.5 fit me perfectly as the Gel-Kayano 32 in size 11. I've just tried these one, so far I feel them comfortable, I walked for 5K steps and haven't had any discomfort with my flat feet and the issue I have with my left knee patellar tendon. I stood up for 30 minutes while I waited for my car at the carwash, no issues. Time will tell about durability, but I can say the looks and comfort are pretty good for such a budget shoe.

Light and comfortable, didn't hold up for a full season

Size: 11.5, Color: Black

Pros:boots were extremely light and comfortable. Cons: if you work in rocky areas like northern California you will only get 1/2-1 season on these. Mine lasted 6 months then the fabric ripped, the soles had holes all the way through to the middle, and the tread wore down til they were smooth slick rubber. If they cost $150-$175 I'd buy 2 pairs a season but at over $300 a pair there are much better options
