I'm a big guy for a runner. 6'1" 220 lbs. Been running for years. Before this shoe I had the Ride 4's and thought they were the best running shoe I have ever run in. Good price + durability + good fit = great shoe for me. The 5's drop the heel height thus less heel cushioning. Ran in them for 2 weeks and developed shin pain. Ordered me some Brooks Ghost 5's to replace them. I think these shoes would be great for a lighter runner, but not for this Clydesdale. It's a shame because I really loved the 4's.
