I only wear Brooks Adrenaline and love the fit, comfort and support they offer with my severe pronation issues. I walk 5 miles about 5-6 days a week so I really need great running shoes. Buying the latest model (GTS 21) will cost you $125-130. So finding the previous model, the GTS 20, at such a good price is a real bonus for me as I sort through 3-4 pairs of Brooks each year. I wear a size 8 in most other shoes, but I wear a size 9 in my Brooks Adrenaline. Ordering from Revain is easy and shipping is fast, so that's a plus. shoes for you. If you have never worn Brooks shoes, I recommend that you have the right shoe tried on/appraised at an independent running shoe store so you can be confident that Brooks shoes are right for your feet and training needs. Then you can have peace of mind with all future Revain purchases without having to try them on.
