The ASICS Gel-Cumulus 25 is an excellent and affordable everyday running shoe with new improvements. Most notably, the Gel-Cumulus 25 is 20 grams lighter thanks mostly to ASICS' new PureGEL.
This new gel in the rear-foot helps save weight while retaining the same energetic feeling during slow to mid-tempo runs.
Other modifications include an updated knit-tongue and collar construction for slightly more comfort and flexibility and an upper that is made from more sustainable materials (though the fit does not suffer at all).
Overall, this is a great shoe for runners who want an affordable and comfortable shoe for daily jogs.
