In reply to UKC Gear:
I have a couple of pairs, half a size apart. I was initially disappointed that they don’t have the stiffness of the previous generation. I used to like the old ones for when I needed power out of small footholds - such as standing on a pebble, while bouldering in the grit.
The new ones are poor at that, way too soft. But I like them for indoor bouldering. They’re great for iffy, small foot holds, roof climbing and smearing. The forefoot seems wide but puts my toes into a semi-crimped position without being uncomfortable. That fit really suits me.
The heel is way too baggy for me. Loads of flappy, loose rubber - which may work sometimes - but I’d prefer a snug fit instead. The smaller size is better but still too baggy.
I’m not sure I see what Scarpa make that fits what the old Booster used to do. Stiff, powerful and downturned.
