Combining an ultra-lightweight upper (with more than a hint of Crocs about it), removable neoprene sock liner, minimal midsole and a quick-pull lacing system, the Ultra is seemingly perfect for the triathlete who wants a speedy T2 and a barefoot feel to their run. Slipping them on, they feel super comfortable without socks and the lacing system gives a good, secure fit. There’s too much excess elastic, though, and it had to be cut and re-knotted.
Once running, the Ultras didn’t rub at all and, during a summer downpour, drained superbly. However, they are extremely minimal (weighing in at 100g) and demand a well-practised light and fast forefoot strike. Our tester has definite minimalist leanings, but even he found the Ultras a touch inadequate and won’t be trading in his racing flats anytime soon.
