Strengths: Price - range from £18 online. Good fit for even tall bloke like me (6'5''). Good vis (even in black) if road running.
Weaknesses: Not as 'fashionable' as some - can see why might not appeal to top level runner.
Overall: If you are running to keep fit, or run for charity it is a brilliant buy. I don't pretend to be a top flight runner - and so I tailor my kit to match - a real value buy for excellent wick away training.
'BETTER THAN THE WR9, SUIT HEAVY FEET, IMPROVED CUSHIONING.'
Strengths: Best comfort for wide, big feet - I am a 12. Fit like a glove after short time. Cushioning even better than WR9.
Weaknesses: Note comments about stiffness - I think this is minor flaw.
Overall: A brilliant shoe and a marked improvement on the old ones. Better than my asics - which shocked me - first stop if you are not overly competitive runner - but need extra cushion due to size and weight.
