Geared for all-day comfort the Nikes are great for European tours, cyclosportifs, and of course, Granfondos.
They look the part of a road shoe and won't clash with Lycra, but they've got a real walkable base too. The tread is deep enough to clear the cleat from hitting the ground, yet it doesn't look aggressive or mountain bikey. However, the extra rubber does mean they can only be used with two-bolt style cleats. They can easily be worn without clipless pedals too, thanks to the replaceable hard plastic cleat bolt cover. To aid walking, the soles have a slight flex in the forefoot, but overall stiffness doesn't disappoint.
There's a good sense of power transfer and no noticeable hotspots over longer rides. A padded tongue, synthetic leather upper and minimal venting does mean they're on the warm and heavy side.
But if you're after a stiff shoe for long rides without the hassle of skating off the bike, then these are a great alternative to Mtb or (more flexible) leisure shoes.
