Sirius Lace LV


(1 customer review)


Precise and aggressive – the Sirius Lace LV is the shoe for your most demanding projects! Equally at home in the gym or outside these shoes excel on vertical and steep overhung terrain where every last fraction of friction helps to propel you up. A full RS rubber sole and medium stiffness midsole provide the perfect combination of sensitivity and friction. The offset lacing system allows you to dial in the perfect fit and provides extra surface area for toe hooks without sacrificing fit or function. Your climbing partners will swear that you’re cheating with these shoes!

  • 3.5mm RS rubber
  • Medium stiffness midsole
  • Lined synthetic upper

    Yes! THANK YOU! Finally, an excellent update and replacement to the Dragon. First, I’ll start with the sizing. I found the 9.0 in the LV to fit nearly identical to my 7.5 Dragons. I wear an 8 or 8.5 street shoe and have always worn a 7.5 Dragon (7 or 8 pair). This fit allows for an ideal slingshot in the heel and as the shoe softens, retains tension in the toe, specifically the pinky toe edge. I’ve only worn these a day, but I can tell that this fit and sizing is on point. For reference, I’m also in a Regulus LV in the 9.0. These, to me, match the Hiangle (new version-not the old smurf feet version). So I’m happy to say that sizing feels very consistent with these models. I have not tried the non-LV versions, so I can’t compare to the volume difference. I can, however, encourage sizing the Sirius Lace LV 1.5 sizes up (to account for the female sizing scale) from the red Dragon to get a nearly identical fit. I’m a man, by the way, with a high arch and narrow heel. The fit is superb. To clarify, I was a 7.5 in Dragons and now I’m a 9.0 in the Sirius LV.
    The lining fabric is a nice update. It slides on well and doesn’t get super slimy when sweaty. The pull tabs are large enough and stiff, to keep out of the way of heel hooks. The lace offset is brilliant. The reinforcement along the eyelets seems like a good idea. It looks cool, regardless. The laces are a bit long, but they can be trimmed.
    As for the rubber, I didn’t have a problem with it being slick, as some other reviews have said. The stiffness of the rubber breaks in quickly. I don’t think it’s anything out of the ordinary. I’ll post an update in a few weeks after checking them out on slippery tufa in Mexico.
    Nice work, UP! You nailed it. I’ll be buying these as long as you keep making them.
