La Sportiva Skwama Climbing Shoe
The Skwama's P3 rand system helps maintains the shoe's aggressive shape, and this combined with the split-sole designed to reduce deformation when edging still provides a decent level of edging stability and support in such a soft shoe. The Skwama really excels at toe and heel hooking, including both the S-Heel™ with an "incompressible rubber insert" to help create a solid and unmoveable hook on holds during torsion-heavy moves, and the elongated toe rubber that provides friction across the entire forefoot.
As for fit, the Skwama features a suede leather / microfibre upper which is lined only in the back. Being part synthetic and part leather, expect it to stretch up to half a size. La Sportiva recommend you fit the Skwama on the snug side for a performance fit. If you're looking for a similar shoe but one that's stiffer and more suited for all-round use, try the Otaki or Kataki shoes which are built on the same last as the Skwama.
