3.5/5
mixed
Reviewers praise
  • Wave plate provides a distinct and effective medial stability mechanism that guides overpronating feet through the gait cycle
  • Firmer, responsive ride that feels snappy and energetic at pace
  • Lighter than previous versions of the shoe, with a slightly wider forefoot
Reviewers push back
  • Firm, structured feel is not well-suited to runners who prefer soft or flexible shoes
  • High heel-to-toe drop may irritate forefoot conditions and requires adaptation
  • Some runners find the upper and midfoot area bulky and stiff, especially at non-standard paces
A firm, responsive stability trainer with a Wave plate that most reviewers praise for its structured support and improved ride, though runners used to soft, flexible shoes may find it stiff.
— best for: Runners who overpronate, prefer a firm and responsive underfoot feel, and want a structured daily trainer with a high heel drop for short to medium distances.
Reviewers disagree · Wave Inspire 21?
Run Moore 4.5/5
Running Warehouse 3.0/5

Reviewers disagree on versatility: the podiatrist reviewer considers it suitable up to half-marathon distances at pace, while the Running Warehouse panel found it less comfortable outside a standard easy-to-moderate effort

The Cloudrunner 2 is an excellent running shoe. Very responsive and the rebound really assists with anti-fatigue; great for long runs. Aside from being a great running shoe the cloudrunner 2 is resilient and versatile enough that it works for cross-training up to medium weights. HIIT Deadlifts 200lbs n DBs, curling 50lbs DBs. No instability in the heel. I was very satisfied with the functionality. MIKE · runningroom.com

I was training for a half marathon and suffered from illiotibial band syndrome when I started increasing the intensity of my runs. Physiotherapist and podiatrist appointments revealed I was flat footed and was overpronating a fair bit. Asics GT 2000 13, Brooks Adrenaline 24 & Saucony Tempus were a bit too narrow for my flat feet but my feet felt comfortable as soon as I wore the Mizuno Inspire 21 Customer · startfitness.co.uk
