Here is my 2 pen’ath in this debate
Invo 8 – 2 70 Very good grip, very light, crap uppers, dry quickly
Invo 8 – 330 Grip not as good, heel causes problems on longer runs better uppers
Walsh – PB Extreme, Best grip, light shoe, good uppers, insole slides around abit
Montrail Highlander – Very good grip on all but deep mud very comfy shoe with support, soaks water up like a sponge and become heavy. take a long time to dry.
Mizuno Harrier – Reasonable light shoe, great for trails, grip is no better than average.
These are all shoe’s I have used and my 2 favourites are Walsh for up to up to 7 or 8 miles and Montrail on the longer runs or trail runs.
