I bought these to replace my pair of Saucony Grid Stabil MC. I have used Saucony motion control shoes for years but lately the Grid Stabil MCs felt like bricks on my long runs (anything over 10 miles). I'm so happy with these shoes. They are light and fast but still supply plenty of support. I have tried to switch to Asics before based on advice from other runners but I felt they provided no support in the arch so I stuck with the Sauconys ... until now. I ran a half with the Mizunos last weekend and I felt great afterwards. Best shoe I have had in years.
