Premier Sponsor:


A good arrow in any quiver, this high-performance slipper is built on a modified Katana last for a straighter fit. With its thin midsole, it grips tough and holds a mean edge all day, with minimal stretching in the uppers. Get some!

  • Uniquely tensioned slingshot rand and double elastic closure provide a second- skin feel and “dialed-in” fit
  • Hidden Heel Shock Absorber (HSA) system takes the bite out of gym and bouldering falls
  • Gimme, gimme, gimme! Slightly down-turned toe makes the Viper a grabbing maniac
  • Thinly padded toe box allows for great comfort especially in thin cracks

COLOR: Yellow UPPER: Leather/Lorica®/Elastic CONSTRUCTION: Slip Lasted LAST: PD55 LINING: Pacific (forefoot only) SOLE: 3.5mm Vibram® MIDSOLE: 1.1mm Laspoflex (forefoot only) WEIGHT: 12 oz

Took a while, but I like it. 4 out of 5 stars

Review by: forkliftdaddy, 2009-11-04

I expected these to fit and perform like the Baracudas I liked when i bought my Vipers. They didn't. I didn't like the fit and they were a battle to get on. Eventually, however, they molded to my feet and I got used to getting them on. Now I really like these shoes for gym bouldering. They fit well enough to use small feet and heel hook pretty dang well for a slipper. The cushion in the heel is nice as well. Good shoe, but it took me a while to be convinced.

Performs well 4 out of 5 stars

Not the most comfortable shoe, but grips very well.

Excellent fit, soft and sensible in the sole 5 out of 5 stars

Review by: martinheynert, 2008-11-16

The last fits my medium with, flat (low volume) foot very well. The elastic closure strap runs over the full width and a length of nearly 10 cm, creating a very reliable fit, better than the "Cobra" or the Anasazi Slipper.

After some hours of use, the sole becomes soft and sensible. If the shoe was selected tight enough, you will still have enough edging power. The shoe will NOT stretch a lot - less than 1/2 size. I use 10.5 UK in street shoes and have this Viper in 42.5. La Sportiva's sizes are made in EUR, so half sizes allow more fine tuning than UK oder US half sizes.

As many La Sportiva climbing shoes, this also has a prominent stitching (seam) insind the shoe just over the big toe, which can result in some pain or skin fissure after a longer time of wear or when heaving damp skin.

I got these to serve as a more aggressive supplement to my much older Spires. They have now become my main shoes. The edging and smearing are incomparable; it's rare that a shoe excels at both. Hooking is good if the shoe is tight enough, but if you get them loose the heel could pop right out. They don't stretch at all. The rubber is durable and sticky. I would recommend these for most climbing styles; they're fantastic!

Review by: slablizard, 2007-09-26

Great shoe, a bit hard to slip in (for my foot shape that is short and wide) but once on they feel like a neoprene sock.
Perfect for edges and holes, good on smearing, good foot support, very comfortable shoe. Great sticky rubber, very precise feeling of the footholds.
A must have for any La Sportiva fan.
