Why does my Nimbus 27 feel less cushioned than Nimbus 26?

I’ve been using the Asics Nimbus 26 (UK 8) for the past 6 months and absolutely loved the cushioning. It really helped with ankle pain I used to have when I was heavier.

Since then, I’ve lost ~12 kg and recently picked up the Nimbus 27 on sale, but only in UK 7 (as UK 8 was unavailable).

It fits with no major discomfort, but I would say nimbus 26 Uk size 8 fits me slightly better though, but can’t complain here.

What I’m noticing is that the Nimbus 27 doesn’t feel as cushioned as my 26 did. 27 doesn’t give the bounce back as my 26 did.

Trying to figure out what’s driving this:

- Is the Nimbus 27 actually firmer/less cushioned vs 26?

- Or Is the difference in effect of cushioning because of the size difference between size 7 vs 8?

Note: I bought the Nimbus 26 (UK 8) from the official Asics store earlier. For the Nimbus 27, I ordered from Flipkart, but I did cross-check the pair on Poizon and everything looked legit, so I’m fairly confident it’s authentic.

Would really appreciate inputs from anyone who has used both models or faced something similar.

Thanks in advance!
