I love Brooks, I have the Glycerin 7,8,9 and 10. I haven't used 9 very often only 10 times and the stiching is comming loose on both shoes where the shoelaces attach to the strap the shoes are useless. I would advoid this one, I am going to buy some Glycerin 7s they are completly better in quality I am sad about this. Brooks you wasted my money but will continue to give you business.
