Precise and aggressive – the Sirius Lace 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

    The Sirius Lace fits true to your street shoe size, they fit perfectly right out of the box, no adjustment period needed. If you’re looking for more high-end performance then comfort, I personally would recommend going a half size smaller, but no more. The craftsmanship is high quality, including re-enforced lace wholes and pull-on tabs. The rubber is soft but firm. Great for edging on a dime, steep terrain as well as vertical and slab and the heel hooks like a champ. Great for hard bouldering and sport climbing. They are a very versatile shoe, also a great choice for indoor and competition climbing.

    As said before the fit of these shoes was perfect the moment i put them on. I have had these shoes for close to a month now and i have to say, the asymmetrical lacing made the fit of this shoe a dream. That combined with the reinforcement on the lacing holes made this shoe an absolute work horse! The rubber itself is as good as it comes, able to out smear and edge a majority of the other shoes i have tried. And also bravo on adding a low volume version for the selection as well.
