Karhu Fast 3, $135
11.0 oz., 9.5 oz.
Fit: The Fast 3 has a relatively slack fit in the heel, but it is also fairly narrow in the midfoot and forefoot.
Feel: Every tester remarked about this lightweight cushioned trainer’s unique geometry with a high heel and a low forefoot. It’s a comfortably appointed, fairly lightweight high-mileage trainer with a rather firm flex pattern. While that shape noticeably helps propel runners forward, several testers said it took some getting used to and a few thought it created a feeling of instability.
Ride: The higher heel of these shoes and 14mm heel-toe drop promote a heel-striking gait, which is fine because the cushioned heel crash pad and plentiful midsole cushion make for soft landings. But the rolling sensation from heel to forefoot is dramatic, producing a considerably different sensation than other high-mileage trainers.
