Strengths: Very lightweight for a bigger runner yet they feel comfortable and hold the foot nicely. I don't want or need massive clunky shoes, despite being 6ft4 and the Fastwitch are perfect for what I use them for.
Weaknesses: The holes in the sole are a little annoying at times as they let in the water! I know they are for weight reduction but they also let in small stones sometimes. Some of the grips wear out/come off quite early on also.
Overall: I love these shoes for regular training and they aren't too bad off-road either. Keep producing them, Saucony, they are easily as good as a certain other brand were before they bulked up their shoes! I'm a loyal fan now!
