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!

    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.

    Fit:
    The Sirius LV is an excellent soft shoe that performs well on most terrain! I currently wear them in my street shoe size (men’s 7 / women’s 8.5), but have tried them out a half size smaller (men’s 6.5) as well. Wearing a men’s 7 in the Sirius LV feels similar to wearing a 37 in Scarpa instincts. For comparison, I wear the Regulus LV in a men’s 6 (quite tight), and the UP Mocc in a men’s 5 or 5.5 (which compensates for the Mocc’s stretch). The Sirius LV has a tight fitting heel compared to many other shoes I have tried, and the arch of the shoe is very defined and quite high (in my case this is a good thing!). The arch of the shoe feels “thinner”/lower volume then the Regulus LV. I have a medium width forefoot, large toes, and a low-volume arch and heel. The Sirius is an excellent fit for my foot.
    Function:
    The softness of the Sirius LV allows you to have good foot-dexterity for steeper climbing, and the laces also allow you to tighten the shoe up for harder heelhooks and small footholds. The rubber (as with all Unparallel shoes) is very sticky. I prefer the Sirius LV heel over the Regulus LV heel for sure.
    Quality:
    I have not had any problems with the Sirius LV’s pull tabs thus far! However, I cannot say the same about the lining of the shoes. Perhaps I just have exceptionally sweaty feet, but I always seem to tear the cotton lining along the stitching near the toe of the shoes, regardless of how I size them. Furthermore, the torn lining bunches up at the toe of the shoe when pulling it on. I have also had this problem with the UP Rise VCS and the Vim. I personally prefer unlined shoes, as an unlined synthetic shoe allows you size smaller because the shoes are able to stretch a bit more. It also maximizes the heel tensioning of the shoe, in my experience. Because the lining on my pairs always seems to tear, I have experienced a bit more stretch in my pairs than I would originally have expected. If Unparallel beefs-up the stitching that holds the lining together, or if they remove the lining entirely, it would be a fantastic improvement!
    Overall :
    The Sirius LV is an excellent fitting shoe for LV feet (not “narrow”, but LV) with a defined heel/arch. It’s sticky, fairly soft, adjustable. I wear mine in my street shoe size, which is a fairly tight fit with no dead space. The torn lining is the only minor problem, but it is definitely inconvenient. The lining may not tear if your feet don’t sweat! Overall a great shoe if it fits your foot.
