This is the perfect shoe for someone that is on their feet 10 hours a day for work. It is a very comfortable shoe to wear with a lot of cushion and support. I highly recommend the Adrenaline GTS 15'. I purchased the Black/Anthracite and the Peacoat/Purple/Salmon. Love them!
I own another pair of Brooks that I bought from Nordstrom, but I had to buy an 8.5, so when I bought this pair, I purchased both the 8 and 8.5 since I was shopping online.
I usually run in size 8 shoes and I ended up keeping the 8. These were perfect out of the box. I run about 2-3 times a week, about 2 miles each time, and these shoes were super comfortable and didn't need to be broken in.
Also, these shoes were not extremely heavy. I used to run in Nike Frees but they had bad support and needed real running shoes when I started running more. I would definitely recommend these.
