Mattwrote a review of La Sportiva Cobra Vibram XS Grip2 Climbing Shoe on February 3, 2013
Familiarity: I've used it several times
This is a decent shoe, but sizing might be tricky, depending on what you're after. Better for face and bouldering. Heel cup is good, so you can heel hook if you size them tightly enough. I would not recommend them for crack climbing (like, for desert splitters). I looked at these as an alternative to 5.10 Moccasyms. Cobras have a more pointed toe box, so that it is highly unlikely your toes will lie flat. I don't have Morton's toe; regardless, 2nd and 3rd toes will not lie flat, even in larger/looser sizes.
Sizing: I wear a street size US 9 mens shoe. I have a size 40 lace Katana, which are sized for agressive face climbing and bouldering. Toes are curled over, so I can't stick them in a crack (or, it's excruciating to use them for crack). I have a size 41 TC Pro, which is sized for all-day comfort and crack climbing (toes are flat). A size 41 Cobra puts my toes in the same position as the size 40 Katanas.
