Ideal for steep, overhanging routes and long bouldering sessions

For the redevelopment of the classic Quantum, we worked with the Huber brothers, Alex and Thomas, to develop an all-around performance shoe for any climbing setting. The Hubers tackle a diverse range of climbs with many different angles and rock textures, so Stealth® C4™ (our most versatile climbing compound) was a natural choice for the outsole.

FIVE TEN QUANTUM MENS CLIMBING SHOE is rated 3.9 out of 5 by 13.
Rated 3 out of 5 by from Great shoe but with quality caveats I've always been weary of Five Ten shoes since they personally do not fit my heel very well, but I decided to try out the new Quantums. Performance wise, they are great. Holds on dime edges and hugs your foot like a glove. Unfortunately after years, Five Ten still has problems with their toe seams. Every Five Ten shoe I've owned, the seam has started separating at the big toe. Hi-Angles, Blackwings, doesn't matter. Exact same with this shoe. I wish they could finally fix this problem as it seems like a big issue if it has happened to every Five Ten shoe I've bought! Shame, there is a lot of toe rubber left on the shoe, the but seam has opened up so much that I cant even climb in them anymore.

Rated 5 out of 5 by from Best shoe ever I got these shoes for all around use and they haven't failed. I've sent 5.13 sport climbs, v8 boulder problems, and granite in Yosemite. I love these shoes

Rated 2 out of 5 by from Good Shoe poor durability Purchased a pair and they had small seam tears after only a month (twice outdoors, mostly indoors) I returned them and have had the same problem with my second pair. Good shoes in regards to performance but I can't recommend for lack of durability. I would recommend the anasazis or hiangles over them.

Rated 5 out of 5 by from Ultra comfortable downturned shoe Bought this shoe to have something with a nice, precise toe and a bit of a downturn. These are definitely the most comfortable downturned shoes I have ever worn while maintaining a good fit. One note: Adidas calls these shoes stiff and I don't really think they are. Other "stiff" 5.10s are much stiffer (for example I have the Anasazi Pros and they are much more stiff). More like medium stiffness.

Rated 5 out of 5 by from Extremely comfy, great to climb in! One of the comfiest shoes I've owned. It fits well even with my low volume feet, though I do have to cinch up the lacing really tight. It's perfect for all day climbing, and the rubber is excellent - my footing feels solid no matter how tenuous the foot holds get. It does smell bad after a while though. I've ended up having to stuff a shoe deodorizer after every climbing session in them, and even then it's still pretty ripe. But I like them enough that I'm happy to put up with it, though my partners may have a mildly different opinion.

Rated 2 out of 5 by from Great performance not so great durability I really liked the performance and the style of the shoe. It fits like a glove and feels great on the rock but after only a couple of months, I started to wear through the top/front of the shoe. And it's not that I've speared and dragged my feet all over the wall. other shoes usually last me a lot longer. I've had friends encounter the same problem.

Rated 2 out of 5 by from Beautiful looking shoe with a steep adaptability c I bought this a week back and it's got my toes bunched up. I've always gotten climbing shoes lower than my actual shoe size. But this shoe being my actual shoe size is quite painful not to mention that the shoe feels more aggressive than it looks.

Rated 4 out of 5 by from Amazing all-around performance shoe! I bought this shoe seven months ago as my first performance shoe. I have a street shoe size of about 9 (9 can be slightly large on my street shoes, but I like my shoes to be very snug) and I bought a size 8.5. In the beginning, these shoes were very tight and were pretty uncomfortable. However, after a few climbs, they loosened up a little bit and were great. After seven months of use, I would even consider getting a half size smaller (but that would be TIGHT). I climb in the 11c-12b range, and boulder on V4-V6. I climb about 4-5 days a week, and these shoes are just about shot, so I am pleased with how they've held up with so much climbing Pros: +Super comfortable after the break-in. Can wear them for hours without taking them off +Very precise, making them good for both techy face climbs and overhung sends +C4 rubber is grippy but not too soft (good performance and solid durability) +Laces make the shoe fit perfect +Can do just about anything you throw at them. I've climbed techy faces, slabby granite, overhung limestone, hand cracks, polished plastic, and just about everything in between. Cons: -After seven months, these shoes smell absolutely wretched. It is unbelievable. It actually smells like poo or bad cheese or something nasty. I attribute this to my feet, but the clarino doesn't help a bit. -Heel hooking is mediocre in these shoes. I can feel unstable or like I have gaps between my heel and the shoe. -Not the best at toe-hooking either (no rubber=duh). -Not the best for narrow feet. I don't have the most narrow feet, but I do appreciate a tight fit. I have to cinch the laces pretty much as tight as they can go -Because they are a "jack of all trades" shoe, you can end up sacrificing some performance when it comes to things like extremely overhung boulders with small feet or smearing, though I have never been stumped by something these shoes can't handle. -Loses the downturn overtime, though I assume this is somewhat standard with so much wear. Overall this is an amazing shoe, and I am sad that these shoes have seen their day.
