i had the nimbus 17, two pairs of the 22, the gel 360, and now the 24. while the 360's were the most expensive out of them, they were also the least comfortable out of all of them. the 17s felt like walking on clouds but the heel support area did not feel like a good fit, i had to step on one side of them before putting them on so they can feel a bit more tolerable. the 22's i liked, but the mesh portion tears quite easily. the biggest problem with buying online shoes is not knowing if they will fit to where you are comfortable with them. i am extremely surprise the 24s fit just right, right out of the box. i can see where some reviewers said it did not feel wide enough for them but for me it was just right since the 22s felt a little wider. back to the 24s. well the inserts felt like they were undulated instead of just flat which is a good thing. they are cushion soft, snug, and very light as well. also i like the tongue portion of the 24's, they seem to add a snugger fit without having to tight the laces so tight that it hurts your feet. these 24s just fit right all around for me. i'm impressed asics.edit: 4/14/2023 the feel, fit, comfort are so nice that i bought another pair and thinking of getting a third. i do not even feel like i need to take them off even after having them on for 9 plus hours. seems asics make a new version and once that version is gone (by shoe size) then its gone and i dont want to take a chance on having to wait for another version that is equally good or better. i have 2 of these and 1 pair of gel 360s which are in good condition but are not comfortable like the 24s. most likely will get another pair that i can rotate them to give them longevity.edit: 21 april 23. so i bought 3 of these 24 series so far but i noticed something about the 3rd shoe. it is the same 24 nimbus series but in the black/gun metal color but there is something different about it. the other ones are in a safety yellow/black and light steel/white. the yellow/black and light steel/white fit identically and just perfect (for my feet). however the black/gun metal colored shoe feels like it is missing an extra layer of cushioning. i have extremely sensitive feet so i can tell the difference. the shoe still fits nice and comfy, but not as cushiony as the yellow/black and light steel/white colored shoes. i would rate the black/gun metal a 4.5 stars while i rate the yellow/black and light steel/white a perfect 5 stars. it just seems odd to me that these are supposed to be identical shoes (aside from color) but there is a difference in cushion depending on the color. i will probably buy a 4th pair because this 24 gel nimbus series make my feet feel so good. i dont want to risk them running out of my size while they work on their next series and it may not fit like these. so i could rotate through them evenly and they will last for years.Bought my 4th pair the cherry tomato color. It fits and feels identical to the bright green and steel white/blue. So I'm very happy with my purchases. Walking on clouds.
