La Sportiva Viper

Very technical shoe. It is great for sticking to small face holds, but not so great on cracks. I liked these shoes, but after trying the Katanas I fell in love with the Katanas. The problem with the Vipers is that it is hard to put them on and remove them, and your feet tend to sweat a lot more on these closed shoes, and they get stinker than usual. They are great for sport climbs, but the Katanas are as good on the rock, and more comfortable.
