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.
- Material: Clarino
- Benefit: Stealth
- Weight: 8.3 oz (234 gm)
- Downturned, Stealth® C4™ rubber outsole (4. 2mm)
- Fully synthetic Clarino upper – No stretch
- Speed-lace closure
- Comfortable, wide last construction
- Breathable Ariaprene tongue
- Stiffness: Stiff

Rated 5 out of 5 by Nickl19 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 SantiV 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 4 out of 5 by Olivo from These shoes are tight I bought these shoes about two weeks ago. They’re really good for edging and the heel feels amazing. I love them!

Rated 4 out of 5 by jackcr 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.
