The Regulus is our stiffest downturned shoe providing both comfort and absolute precision for any angle and all styles of climbing. The unlined synthetic upper provides a soft feel on foot while maintaining a perfectly snug and secure fit. The full RH rubber sole and stiff midsole provide exceptional edging ability and the extended rubber over the toe box provides extra friction for toe hooking. The highly tensioned heel and sling shot rending locks your foot into the shoe providing extra power and bomb proof heel hooks.

  • 4.2mm RH rubber
  • Stiff midsole

    These seem like a great shoe, well designed with tacky rubber. I was hoping they would be sized similar to the Five Ten Hiangles (my go to shoe) but I couldn’t get my heel into the same size Regulus. A great looking shoe, very stiff, but not for the wide footed climber. A side by side comparison shows the Regulus is much more low volume.

      Hi Britt,

      Thanks for your feedback and first version of Hi Angel was made of leather which allowed more room by stretching and Regulus are made in synthetic(non-stretch) with extra sling shot supporting your arch and reducing heel volume. Yes overall Regulus has less volume and tight fit comparing to equivalent model. Thanks again for your feedback.

    I’ve waited to review so that I could give these things a good break in period. That being said, it has been a LONG break-in period. The rubber is definitely on the stiffer side, and for some reason has taken considerably longer to break in than shoes in the past..

    That being said, I love these. The rubber on the top is soft enough to deform for your toes and not lock them into a semi awkward position. The synthetic upper has allowed the shoe to fit the same as the day they came put of the box, so they’ve kept that performance fit (but don’t downsize too much! They are a smidge narrow).

    I love the rubber. I’ll say, I didn’t right out of the box, it is stiff and wasn’t super sticky right off the bat (and, being stiff, I didn’t get the flexibility out of the sole I was used to), but it has broken in well and has lost all of the initial slickness I experienced.

    My biggest complaint, honestly, is that the straps are a little long, so, even cinched up, they dangle over the edge of the velcro and can catch on things and stuff.. Not a big thing at all, but, I find it sticking to my chalkbag a lot…

    All in all, a great shoe of great quality. I love the shoe, the toe hooking in these things is phenomenal (there are little slices in the toe rubber in the PERFECT spots). I’m also a huge fan of the heel. It might be a bit narrow for others, but it fits me perfectly and I’ve cranked on some sketchy heels in them and have not slipped once!

    I’m stoked to check out others in the new line!

    Excellent shoe. Similar to the Five Ten Hiangle, but better. I haven’t had it long enough to rate long-term durability, but so far, this is the best climbing shoe I’ve owned. Very very sticky rubber. It is a perfect blend of comfort (for an aggressive shoe) and performance. I have a long narrow foot, so the fit is better for me than the Five Ten Hiangle, as the Regulus has no stretch and is slightly lower volume. In addition, I feel that the Regulus’ rubber has better friction than the Hiangle. Toe hooking is excellent. Unlike other manufacturers, this shoe actually has a high-friction rubber on top of the toe, not just protective rubber, making toe hooks easier. The heel is also excellent, with no slip.
    When fitting, a good start would be street shoe size. I think this shoe might be 1/2 to 1 size down from a Hiangle for reference.
    Seems like too good a review, but I honestly don’t have anything bad to say about it so far. It’s a great shoe. Perhaps a cool electric blue color upper to match the pull tab would be nice. It’s a little drab.

    Have been using these for a while now and has quickly became a favorite aggressive climbing shoe. The stiffness of this these remind me of the old V10s but with the upper being comfortable enough to fit like a glove without any painful pressure points and a better fitting heel.

    I was looking for stiff performance shoes and this pair was exactly what I was looking for.

    For reference, I wear a size US 7.5 in the Five Ten Hiangles and a EUR 38 in the La Sportiva Skwama. I got a size US 8 for the Regulus and they fit perfectly, even better than the Hiangles. There was no dead space nor hot spots, the heel was snug, and the lining was super comfortable. The only uncomfortable part of the shoe was the elastic band on top. It has a bit of a rough feel and is something that can be improved on.

    I love the rubber on these. They’re super stiff so they provide good support on tiny edges. The rubber is sticky as well so I have no issues smearing on the wall.

    I use the shoes primarily for bouldering but I also use them for sport climbing. If you want super comfortable shoes that you can keep on for the whole session then these aren’t the shoes for you. I remove them after climbs to rest my feet.

    Super pleased with these shoes!

    I really enjoyed climbing in these shoes. The rubber is tacky and the overall fit is snug and secure. I will say though that the break in period is grueling. I bought the same size shoe that I tried during a demo but the shoe was just a nightmare to break in. Even after the shoe became more fitted to my foot, getting the shoes on was still difficult. If fact I only retired my first pair because I accidentally tore off the pull loops on the heel when trying to get the left shoe on. Going to try a size up hoping that I get a similarly snug fit with easier entry. Otherwise, the shoe performed great and felt great after breaking in. Side note to Unparallel; please don’t change the color of these shoes in future iterations, just leave them black. Shoes DO NOT NEED WILD BRIGHT COLORS. I mean really, neon anything is going to look childish.
