Booster Climbing Shoe

Scarpa made the Men's Booster Climbing Shoe for anything overhung at the local gym, sport crag, or boulder field. It has the same aggressive downturn and sharp asymmetry as Scarpa's Boostic Climbing Shoe, except Vibram's XS Grip rubber gives this shoe as softer feel for more sensitivity and friction. It features a unique PAF randing system that prolongs the shoe's downturn and pushes all the power directly to the toe for a technical performance. Expect the microsuede upper to stretch a half size to full size for a customized feel.

Amazing soft + aggressive shoe

I've used it several times
True to size

The new Booster climbs great and is the only really aggressive shoe I can use comfortably. Usually banana fit hurts my feet badly, but the Booster is super comfy because of the dreamy materials and softness. It is the nicest built shoe I've ever used. I bought 45's for a good fit after 2-3 hours of climbing with toes curled. I'm an 11.5 street shoe, and that's half size a bigger than I wear in Instincts. Fit is better than the very similar shaped Boostic since they're much softer. Performance is awesome outdoors. Plenty of big toe power even though it is a really soft, sensitive, sticky feel. If you have strong feet this makes them good on micro-edges, smears, and everything in between. The toe is pointy enough for small pockets. I'd pick a stiffer shoe for really sustained front pointing.

Great shoes

I've put it through the wringer
Runs large
Size Bought

Been using these for a few months now. They have great sensitivity and precision, much more than other stiffer shoes I own. You can really feel the footholds and gives me a lot of trust in my feet. I primarily use them for rope climbing, but are pretty good for bouldering as well. Sizing: I normally wear a 43 street shoe, I ordered a 41.5 in these. Took about a month of climbing to fully break in. They were pretty painful at first, primarily due to your big toe being pushed up against the rubber of the top toe box. After they stretched some, they have a really good fit for my feet, and are fairly comfortable and form to my feet very well. I would probably advise against sizing down as much as I did to avoid the pain of the break in period. I have another pair of scarpas that I ordered 1 size down and they fit pretty well and are slightly more comfortable but still a snug fit.
