Strengths: Mizuno have just released Wave Inspire 6. No real change to the shoe. Lightweight, firm responsive cushioning that's consistent whether your running a 5k or a marathon and so, so comfy. And not that it matters but the new ones are a really cute pink. These shoes last much longer than most others tried in the past.
Weaknesses: Can be a tad wide across the forefoot so not really suitable for those with really narrow feet.
Overall: These are brilliant shoes for all distances. Lightweight, supportive and flexible they're great straight out the box.
