AI summary of 4 reviews · as of Jun 2026
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.
What they 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
- Improved midsole foam delivers a smoother, softer feel than earlier iterations without losing responsiveness
- Well-suited to daily training distances and can accommodate orthotics
What they knock
- 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
- Firmness can cause the shoe to feel sluggish when slowing down or speeding up significantly

What owners single out
Buyers' weakest aspect (durability at 3.5) doesn't directly overlap video reviewers' firmness/stiffness concerns, though the firm construction may contribute to uneven wear patterns.
In their words
“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 ”

“Tread is wearing fast. I don't run ever, these shoes i bought just for dog walking.I've had for a month and parts of the tread are flat i dont think they will last very long at all. They are very light and comfortable but are very expensive for what you get”
