SCARPA Booster Vegan Rock Climbing Shoes - High-Performance Sport Climbing & Bouldering Footwear with Enhanced Sensitivity & Support | Perfect for Indoor Gyms & Outdoor Cliff Adventures

I was looking to get a more aggressive climbing shoe for indoor bouldering and decided to get these. Perhaps my biggest concern was durability. I wanted a shoe that would last me for as long as possible (since I'm not made of money and can't buy new ones ever other month). After using for a couple of months they have stood up quite well. I still have lots of life left in them and they look barely worn at all. Compared to the instinct VSRs I own, they probably hold up better. The boosters are not without their cons, however.Sizing wise, I wear a 44.5 or 10 us in the instinct VSRs and got the same size for these. They fit well with no dead spots for me. I will say, the highly asymmetrical shape and aggressiveness make them more uncomfortable than the instincts (which makes sense) so probably not a pair you would go for if comfort is a primary concern. That being said, I wear them for about 15 minutes at a time before needing a break.They are quite grippy and are obviously best for a steep overhang climbing. They do work quite well for more slabby and less overhung routes though. Standing on small toe chips is fairly effortless your feet feel secure. I will say, if you climb on big slabby volumes, the instincts are more ideal and give you better control and security.Now! This was probably one area that I underestimated previously but the boosters excell at ventilation especially compared to the instincts. Ultimately, that means your feet don't reak after you've used the shoes for a month. After a couple months of use without washing they will start to smell but it is nothing compared to the instincts. Way to go scarpa! I Didn't even know I cared until the boosters.I'm conclusion. These are great shoes to use indoors! They are durable, breathable, and ideal for overhangs while still being versatile. They are a softer shoe than the instincts so maybe less ideal for big guys like me (6' 2" and 200lbs) but they definitely are worth it if you're looking for a bit more performance.Hope this helps. Enjoy the climbing journey!
