This is a review only regarding the sizing of these shoes--I have yet to climb in them and therefore cannot comment on their performance. The four stars above are therefore meaningless.

I recently purchased a number of sizes of this shoe for our organization's climbing supplies. The first thing I noticed was the length of the shoe, and therefore tried on a couple of pairs to see how they fit. In short, a women's size 12 Lyra (marked on the box as a 44 Euro) is approximately the same length as my size 41 (Euro) LaSportiva Miura. Now, the Lyra is much higher volume and has a more aggressive toe, meaning I could curl my toes more than I typically do in the Miura, but nevertheless, I felt that were I to wear these shoes, I would be in a 43 Lyra (size 11 W) at best, whereas the size 41 Miura is rather roomy--when I am looking for higher performance, I wear a 40 or 40.5.

All this said, I am often a slab and crack climber and so don't love higher volume shoes with downward pointed toes and so the fit of the Lyra felt a bit different to me than my standard fare.

These run very small - size way up
