Comments: Definitely get 1 full size up. Size 10 in my Adidas adizero is size 11 in these T7. Extremely light. Not a lot of cushioning in the forefoot for med/forefoot strikers like me (5'11, 150). They were comfortable for me right out of the box, raced a 5k in them the next day, and didn't even notice I was wearing them, which for me means they fit well and ran well, at least for my 5:50 pace. I don't know how long they will last, as the forefoot looks to wear fast. I would not suggest running more than a half marathon in these unless you are a very light efficient runner. Still a nice shoe.

Comments: Not as comfortable or breathable as the T6, but still fits the unique category of a racing shoe that isn't entirely flat (gives some Achilles/calf protection). Despite what the current description says, you should order .5 size larger (so a 12 if you normally wear a 11.5).

Comments: Since the T5, things have gone downhill. The T7 simply does not give you a feel for the road which the T5 had. Please bring the T5 back.

Comments: T7 feels like the previous T6 with one notable change. The achilles guard sits more straight up instead of digging into the achilles which is a relief if you have sensitive achilles. However, there is one drawback with this change. Over certain surfaces (mainly grass) your foot could "slip" out of the shoe slightly if you try to do an all out sprint (happened twice and had to back down or else lose the shoe). But overall, a solid racing flat over 5k-10k distances (have not tried other distances in them). Forefoot striker, 90 miles a week, low 16 minutes for 5k (road & track).

Comments: Very light weight shoe, great for races, fits tight though. The Green Silence is more comfortable in my opinion. Buy at least a 1/2 size up, and wear socks because of the seams.
