HAM wrote a review of La Sportiva Speedster Vibram XS Grip2 Climbing Shoe on February 6, 2011
The Sportiva Speedster is truly a step in the right direction for climbing shoes. These shoes have a steep learning curve. The Speedsters have no edges to stand on only an inch wide band of rubber over your big toe. They will allow you to grab holds on overhanging terrain with the greatest of ease, but will spit you off of the biggest footholds on anything less. That is until you clean up your messy footwork! These shoes will change the way you approach climbing for the better. I have been thrashing theses shoes for the past year indoors and out and they are a solid performer, as long as you can keep up..
