I have clocked on a few miles on my Brooks Ghost 13 shoes and I absolutely love them. I upgraded from Brooks 9 series, which previously held the rank of top running shoe in my arsenal. How could they possibly improve on the 9? I opted for the Ghost 13 over the 12 since I keep shoes for a long time and I wanted to have the most recent features.
The 13 is a well-balanced shoe with neutral pronation. It feels lighter than the the 9 with the "Engineered Air Mesh" upper, it's a breathable fit. The DNA Loft is an improvement as well with a very responsive cushion, not pillow soft, but what you would expect during a run. I liked many of the colors schemes, and ultimately gave the choice to much more fashion-savvy daughter.
I settled on color: 053 - Black/Grey/Stormy. The combo almost looks almost navy blueish, really sharp. From a sizing perspective, I go with a 10.5 US in a D-width. The sizing from Ghost 9 to Ghost 13 was true and accurate. I made no sizing changes between the series.
Brooks is simply the best running shoe out there. Weber's decision to focus Brooks on running shoes and do it well has been impressive. I will continue to "run happy" with Brooks Ghosts.
