Strengths: You can pick them up for around £50 these days. They look quite stylish. Ok for short training runs.
Weaknesses: The cushioning required for long runs is just not sufficient. More than 12 miles will leave your feet with bruises.
Overall: I ordered a pair of Wave Inspire 6s and these were delivered by mistake. I should have returned them but decided to try them out. Mizuno have completely discontinued the fantastic Wave Inspire 6s and created what is a completely inferior product. Absolute rubbish - do not waste your money!
