Pros-So I was extremely excited when I got these bad boys. The break in period was rough, but after 5 or so gym sessions they had completely molded to my feet, and these days I can keep them on comfortably for 20-30 minutes. I finally upgraded from the classic beginner La Sportiva Tarantulas, and the Boostics have performed phenomenally. Vastly improved my footwork for those little baby foot holds. The rubber on the top of the toe, while uncomfortable at first (you will develop a callus there), is great for any toe hooks and bat hangs, if that's your thing. Cons-There is only one con. These things dye your foot BLUE. Like, super blue. Like you dipped your foot in easter egg dye. Every time you wear them. At first I thought it was because they were new, but I'm about 30 sessions in and it has only worsened. I have to use a pumice stone to get it out of my skin, but usually I just opt out and leave my feet blue. It is a very strange look.
"Surprisingly comfortable and easy to break in"
These are my second pair of climbing shoes, the first being the Scarpa Force. I think I downsized about a size and a half US. Every time I put them on, I have this idea in my head that it's gonna be a chore. But once I start yanking on the tabs it feels like a nice suction that pulls my foot in. By no means do I want to wear them all day without a few breaks, but they feel great compared to my expectations for an aggressive shoe. The colors are also fun!
I wear a street shoe size 7, downsized 1 full size-Euro 37. Fresh out of the box I thought I was going to have to return-it took me 10 minutes to put each shoe on.I could wear them for about 25 sec before ripping them off. After 4 weeks of break in, I started to wear these for regular climbing sessions. They have molded perfectly to my feet! I have used them mostly for bouldering with the intent to use them ultimately for sport. I had the opportunity to try them at Squamish and couldn't have been happier with their performance! Negatives: the break in period was a tease! but worth it. Also, the rubber on the inside of the shoe can cause some major blisters on the tops of your toes.
