Essentially a Miura slipper
Great shoe, a lot like the Miura lace, they're versatile, high performance and sleek.
The main difference with this shoe is that its unlined leather upper and thin (3.5mm) sole make it more flexible and sensitive, but less precise than the Miura. This is great for overhangs and gym climbing, but makes them suffer on edges, especially as they break in. The vast amount of elastic needed in this shoe to keep them snug on the feet is also less comfortable than a lacing system, because you can't eliminate pressure points.
On the upside, they are not too expensive, and go on and off really easily. I sized them they same as my Miura's and the fit just a hair tighter.
