The La Sportiva Miura VS is the slightly stiffer version of the Miura Lace, as well as being better suited for wider feet. Unlike the original, the Miura VS features La Sportiva's P3 rand system that makes the shoe slightly stiffer and less likely to lose its shape after stretching. Aside from that, the shoe is mainly the same. It features a slingshot rand and a Powerhinged sole that, when small edges are weighted, prevents the shoe from stretching in the front half of the shoe to keep power and control on tiny holds. An aggressive downturn does mean it can still hook onto overhanging holds and slot into pockets, however! Many people wear these shoes tight for technical sport climbing and high-end bouldering, but others who have worn them looser say that they perform just as well for crack climbing, trad routes, and big wall climbing. They have a leather upper with a synthetic lining (none under the foot however so as to not reduce sensitivity), and so will probably stretch about half a size.
