I had a great day two new shoes showing up at the same time the Pure Drift and the Salomon Sense Ultra. Already posted my initial thoughts on the Ultra in the Salomon area of this forum. I have been a big fan of the Brooks Pure series shoes and really like the new Pure Flow 2. The Drift is a totally different shoe than any of the other Pure shoes as this one has the option of a 4mm or zero drop and is very light weight. My 11.5 weighs in at around 6oz with the insole removed. I did the 4mm drop option in my test run. I really like the wide toe box and the cushioning on the shoe is more than I anticipated. The fit on the shoe is great a glove like fit is the best description I could give. Sizing wise they run true to size as I take a 11.5 in my Pures and the 11.5 in the Drift fit perfectly (something I was concerned about since I had no opportunity to try this shoe on). The shoe has a great road feel but not bone jarring. I did not like the sound the shoe made as the Pure is very quiet footfall. The shoe felt fast because of the low weight (equal to that of some of my racing shoes). I got the black and yellow color and it looks great. All in all a very positive initial reaction.
