The Booster is a soft, precise climbing machine. It excels at climbing overhangs, roofs, and small holds in steep terrain. It was a joy to test these shoes on classic European limestone routes, and they even surprised us by performing well on more vertical granite faces. But it's important to point out that the Booster is really a specialized shoe – and a very expensive one, at that – specifically designed for steep climbing. It doesn't edge super well compared to other shoes we've tested, and it certainly isn't designed for crack climbing. But as a specialized tool for bouldering or steep sport climbs, the Booster is well worth your investment.
The Booster is a technical and precise shoe that works best on steep, technical terrain. Great for bouldering and sport climbing as well as the ever blossoming indoor climbing market, I’d recommend the Booster for climbers who want a precise, aggressive and sensitive shoe with a lot of toe power. The twin velcro straps, DTS rand and PAF system give a secure and powerful feel to the shoe and the light, thin materials and general lightness of the shoe, offers incredible levels of feel on steep terrain (well ALL terrain actually).
At £145 the Booster is the most expensive shoe in Scarpa's rock shoe range (with the exception of the highly specialist Maestro Alpine, that comes in at £220). As a result of this, and that differences between it and the others within the range are subtle, it might make people cynical about investing in it; however, what I'd always suggest to such cynics (myself included) is to try them all on and see which one works best for you. Whilst it is subtle, the Booster does provide a degree of edging ability which the Furia Air, Furia S and Drago don't, but with the added benefit of retaining the same degree of sensitivity. The only thing that lets them down is the heel, which does appear to be at the slippier end of the spectrum.
Overall, the New Scarpa Booster is a great addition to the Scarpa line up. With its comfort and sensitive nature, it fits right in between the Scarpa Furia and the Scarpa Booster S. However, to consider this shoe the evolution of the Booster S line is a mistake. Although the shoe improves on the heel of its predecessor (pun intended) and retains the same feel in the toe box, the mid portion of the shoe and the sides of the heel seemed to have reduced the overall power of the toe box resulting in a lack of all around usability.
The Scarpa Booster S was the king of all shoes when it came to navigating every type of terrain, from slab to overhanging rock, and in our opinion, the New Scarpa Booster can’t seem to get the job done as a replacement tool for a tool that never needed replacing.
I am a fan of Scarpa shoes, I really think they make a high-quality product, it feels like the technology that they put in really helps the climber and it’s not just a gimmick. I love looking down and seeing that precise edge. It requires a slight tweak to the way you climb but you can be almost less precise as the softness makes holds better. But if you level up your climbing, really focus on your feet then the booster will re-pay you. The shoe is waiting for you to get better, which is a cool feeling. For sure it’s a specialized shoe, but if you have wider feet you might struggle. However, if you're in the market for something high end then the Booster is for you.
When the Booster first came out in 2007, its fierce torque plus balletic precision made it a redpointing beast. The Booster got a big makeover for 2020 with Scarpa’s new PAF heel, which splits the tension rand behind your Achilles, letting you downsize for max precision. (I dropped 1 size from the Booster S.) The resulting “bite” on micros is peerless, and the new heel is a soft, suctiony dream. The Booster has a Flexan midsole and 3.5mm XS Grip 2 outsole, and uses the same Alcantara toebox material as the Furia Air, conforming to this key pressure point over time.
