Ninja Climbing Shoe

Sneak your way to the top of competitions by training and seeking sit-starts on difficult boulder problems in the Boreal Men's Ninja Climbing Shoe. Soft and sensitive, the Ninja thrives on delicate smears, technical slabs, and microscopic edges. Its forefoot rand tensions the Ninja in a moderate downturn for vertical to overhung routes, and the Texon midsole is soft enough for slabby sections. The FS-Quattro rubber sole stays sticky for seasons, and the split leather upper features a rubber toe for solid toe-hooks.

  • Subtly aggressive climbing slipper for boulders and slabby routes

  • FS Quattro rubber sole gives traction and abrasion-resistance
  • Split leather upper with elastic sides for secure slip-on

Sizing info - good sensitive slipper

I've used it once or twice and have initial impressions

Just got the shoe and haven't had the chance to really climb in it but wanted to provide a little info on sizing. I got this as an indoor bouldering slipper, so wanted something a little more comfortable. Street shoe: US 10 La sportiva python: 41.5 La sportiva testarossa: 42.5 I bought the ninja in a size US 10.5, as the comments about the small opening got me worried. I'm glad I got the size I did as I can barely get my foot in the opening. Once on, the shoe seems comfy with no real dead space, so very happy I went with the size I did. Got a chance to use these outside and was really happy with them. They are soft so they work great on overhanging problems and smearing. Not as good edging, which is to be expected. Really comfy, a wider toebox than pythons, more similar to a skwama. I was nervous about the zenith rubber, but it seemed to grip the granite smears really well and was very sensitive. I got these on sale for $90 and am very happy with them.

Sizing is an issue but...

I've used it several times

I bought these through Amazon but they came from Backcountry. I ordered them in 12(US)) This is the size of my Garmont Dragontails. I almost returned them. I could barely push my feet through the elastic opening. Even after using the front loop, rubber didn't seem that sticky. Some other reviewers online have experienced the same. They were unbearably tight. Put them in the closet for several weeks., Then, I started to use them just for 30 minutes at a time. They did stretch enough, rubber started to stick. Now, I can wear them for an entire session (less than 2 hours) they are precise and surprsingly stiff in the right places. Worth the initial pain, I use them constantly.

Great shoe, runs small

I've put it through the wringer

Awesome show, great for a newer climber aggressive shoe. They run super small (I fit 44 in la sportiva) but I got a 11.5 (US) in these. Originally got a 44 and had to send back and get new ones. Fantastic work with these
