for something "lickety-split"? This incredibly light road-racing Brooks T7 Racer
Unisex Running Shoe is the fastest in the pack, with a new eye-catching upper
for fly-by style. The streamlined asymmetric upper works with the anatomy of the
foot to perfectly wrap the arch securely from start to finish. Triathlete
Chrissie Wellington races in the T7 and calls it "an amazing shoe!" She was
rocking a pair when she smashed the world record at the Ford Ironman Arizona in
November. Available in men's sizes only. (For women it is suggested ordering 1.5
sizes smaller than what you usually wear).
Note: As this shoe is a very lightweight, minimal support racing flat, the
vast majority of runners will not find it "enough shoe" for a full marathon. If
you have a light frame and a biomechanically efficient stride, however, you may
be able to get away with it. Brooks suggest you work up to it in several half
marathon-plus races beforehand to see how it works for you before running in it
for a full marathon.
