This is my second pair of Pro Grid Guide 5s, I was due for a new pair of running shoes and couldn't pass up the Amazon price. They were originally recommended to me by a shoe specialist at Sports Basement when he saw I have a slight overpronation.  I run about 10 miles per week, and these shoes really make my feet feel great. No shin soreness and I don't feel like I am dragging my feet. I am generally a 7.5 in regular/dress shoes, an 8 in other brands of sneakers, and I need this pair in an 8.5. I My shoe specialist reminded me that our feet swell when we run and we need plenty of space inside the shoe. They feel good when I run but I do feel a bit like a Sasquatch because they are larger than I am used to!
