    So far these shoes are some of the best slipper-style shoes I’ve owned. I usually climb in Five Ten Moccasyms, and these shoes incorporate everything good about the Moccasyms into their design, especially their fit and sensitivity. The toe rubber, tighter heel-cup, and slightly softer sole rubber is great for gym climbing, although the UP Moccs’ edging capabilities are lacking compared to some other shoes. The sizing of the UP Mocc compared to the Five Ten Moccasym is similar, however I downsized a half size from my original Five Ten Moccs for a *slightly* tighter fit. I also noticed the heel cup was slightly narrower. Overall a great, well rounded shoe for someone who prefers the natural feel of climbing in slipper style shoes, but wants something that solves the common downfalls of the original Moccasym (i.e. loose heel, no toe rubber).

    The Up Moccs fit me amazingly well! So well in fact that the heel can be tricky to get out of when taking them off due to a vacuum effect that happens. You can actually hear it release when pulling them off. The heel is more tensioned and the rubber across the toe helps with toe hooks and durability in cracks. This shoe is a winner!

    Just got my Moccs – they fit just as comfortably as my old pair of slippers. The top rubber on the toe seems like it will be awesome in cracks. Climbs really confidently. Construction is solid. I can’t want to see how well they hold up over time.

    These shoes are my new standard. My first pair held up really well to a couple of trips and lots of time in the gym. I sized as suggested on the website and they fit great, though they do stretch a little over time. Super happy and 100% keeping a pair of these on hand.

    I had an opportunity to try the Up-Mocc today at CRG – Rochester.. Despite my narrow (B) feet, I was impressed by the fit and function..

  6. Matt C.

    Got to Bishop and realized my shoes were not to be found so I went to Mammoth Gear Exchange and took the opportunity to upgrade my old re-soled shoes. I settled on the Up-Mocc and picked up a pair of US Men’s 7.5 (EU40) for my feet that measure Men’s 8.5 D. The Up-Mocc fit perfect for climbing and I took off to the Happy Boulders. After two days of sending new problems I was super satisfied with this shoe. I didn’t feel the urge to take them off and stretch my feet between problems and I trusted them enough to flash Heavenly Path and commit to heel hooking on Ketron Classic. Grippy, edgy, and comfortable for long climbing days. These will be my new go-to all-purpose shoe. My friend was climbing in the Unparallel Vim and I could see those being really nice when you need a more aggressive arch.

    Amazing shoes. I fit these less aggressive because I was having toe joint problems, and even with the relaxed fit the heel stays really well. The toes on these are super durable and still going after months of regular use. Sensitive. The toe rubber cap is awesome. Overall, definitely will buy again.

    After falling in love with the 5.10 moccasyms but them basically being impossible to get hold of I thought I’d try these out, and what a great decision.
    They fit the same as moccasyms however don’t strech as much, assuming due to larger toe rubber.

    Heel feels as good as you can get with a slipper, rubber is great out of the box.

    The build quality is great and have out lasted any shoes I’ve ever had, make a great pair of edging shoes out of the box and as you wear them they become a great gym shoe.

    Couldn’t reccomend enough, also customer service from dark venture was great, good work all around!

  9. Bryan Ebert

    My new favorite pair of shoes. These shoes do everything and stick to everything. Perfect all around pair.

  10. Chris F

    Awesome shoes. Love them for cracks, slabs, and all day routes. The sticky rubber almost feels like cheating on JTree slabs (but I’m not complaining).

    The only problem I’ve experienced is the front of the toe patch beginning to peel up after the very first pitch of climbing (#3 camalot size crack). This was a little disappointing, but I still recommend the shoes.

  11. Zac

    Killer shoes. I switched to the UpMocc after the Adidas Mocc became garbage after they switched leather. These have been slightly less comfortable but but slightly better performance than the old 5.10 Mocc. I’m not 100% sold on the added top rubber as it limits the leather from breaking in to the shape of your toe knuckles (I size mine tight) thus reducing comfort. Additionally my first use of the shoes resulted in this upper toe patch rand peeling back from the toe backwards. I plane to reinforce with barge cement and try reglueing. I would suggested updated models either scoring slits into the leather where the toe knuckles are located to add more stretch or even treating the leather with a bargecement like coating similar to how creek rats treated their Mocc’s. The leather on the UpMocc is far superior and incredibly thick which increases durability but also lengthens the break-in time. Not a negative, just a heads up to people wondering when they will break in. Lastly, I am a 10/10.5 street shoe and I size mine to a 8.5 same as my original 5.10 Mocc’s.

    I love these shoes. After 3 months of outdoor climbing they are still great! Way better than my Moc Anasazi. The heel feels really locked in for a slip on. I wear a men’s 9.5 and got an size 8 min these.

  13. Kyle (verified owner)

    This is an excellent shoe. Much better than the five ten moc, with better construction. That said, why neon yellow???????? Please change the color for future versions, this is extremely ugly.

  14. m.adrianlaguisma (verified owner)

    New favorite pair of shoes. Sticky and sensitive rubber with great comfort and performance combined.

  15. Naomi Oregel (verified owner)

    Best all round shoes! The edging and comfort in these shoes is unparalleled (yes pun intended). They are definitely true to size but I downsized half a size for an aggressive fit. Even though I had to wrestle them for a few minutes to put them on, the second they were on they felt amazing! First time climbing in them I literally said wow the whole way up. Felt like I had been climbing in this shoe my whole life and it was already morphed to my foot. I could climb at my grade straight out of the box, impossibly comfortable for how tight they were. These replaced my old 5.10 Anasazi VCS that you can’t get American made anymore. Those were my favorite neutral shoe, and the UP Moccs made those feel like climbing in a plastic bag with holes in it. You can smear on nothing or stand on razors, and they won’t let you down. 100/10
    Sizing: Street size 5. Bought 4.5. I have wide, boxy feet.

  16. Kramer Canup

    My favorite all around climbing shoe. The soles are as sticky as the classic Stealth rubber, extra rubber over the toes protects the leather really well, comfy out of the box and the green color is super rad! Highly recommend to anyone looking for a solid comfy all around shoe!

  17. Liz

    I intentionally sized these things huge on me for crack climbing. Used them in the gym out of laziness and was surprised at how well they performed! Haven’t had a foot slip in the past 4 months, they’ve done well on up to V7 slab. And they’re so damn comfy I don’t even take them off between climbs or on long multipitch days. These are THE sandstone climbing shoe. In love😍

  18. Tucker

    My favorite shoes by far. I am 9.5 US street shoe and sized these at 8.5. For reference I have scarpas at 42.5, and la sportiva shoes at 8.5 or 9 depending on the shoe. The moccs were pretty painful at first but after a month or so of wear they fit like socks. The rubber is super sticky and very sensitive which is probably my biggest plus over other shoes I have which can sometimes feel like bricks on your feet. My other big up is the toe patch. These things toe hook incredibly well and for some problems they’re the only shoe I can use because of how much better the toe is. Highly recommend, will be resoling mine for a long time.

  19. Joseph (verified owner)

    I love these shoes. Climbed in them all summer and fall of 2020, outside and in the gym. They became my go to shoe for everything. I don’t know if it’s the ease of use and comfort or if it’s just that they perfom so well. Great all around shoe. I’ll be getting them resoled soon and hopefully for many years to come. Thank you Unparallel.

  20. Mitchell (verified owner)

    Love these shoes! Great for multiple sessions per week of both indoor and outdoor bouldering so far. Very comfortable and easy to wear for extended periods of time but also easy to take off in-between problems.

    I am typically a street size 9 in most shoes and got these in a 8.5 and am very happy with my purchase. I have a slightly higher volume foot and find the 8.5 to be perfect. Highly recommend!

  21. Olivier (verified owner)

    Love it for indoor as well as outdoor. I needed a new Mocasym but the heel and lack of toe patch always bothered me. With these the heel stays on and there is plenty of rubber for toe hooking. Super confortable right out of the box and sets i after 3 session .
    Loved it on slab and crack. Great for bouldery routes on hot days.
    Not super secure on tiny granite egdes and knobs. I am also super impressed by the rubber.
    I wear U.S.10.5 and bought those in 9.5. I don’t like extremly tight fit but didn’t want a sloppy shoe. Hope it doesn’t stretch too much, only time will tell.
