The Unparallel Sirius Lace is a high performance climbing shoe equally at home in the gym or outside, excelling on vertical and steep overhung terrain. 

Developed using years of elite level feedback, the Unparallel Sirius Lace is arguably the brand's highest performance rock shoe. Almost indistinguishable from the Five Ten Dragon, one of the best performance shoes of the last decade theses shoes are best used where every bit of friction/contact counts. Offset lacing allows you to dial in the perfect fit and the ribbed lacing improves hold and minimises the risk your shoes coming undone. 

On the base of the shoe is a full length Unparallel RS (Real Supreme) rubber sole, which competes blow for blow with the best rubbers in the business. This is the softer of Unparallel's two climbing compounds, and is slightly sticker than the RH formula. This means whilst grippier on smears and slopers, it is a little more prone to deformation on micro edges and will wear out slightly faster. The midsole is a medium stiffness, making it a good platform across a range of angles. 

Who are Unparallel?

Whilst you mightn't have heard of Unparallel shoes, they are far from new to the climbing shoe game. Based out of their Redlands factory in Fullerton, California, Unparallel rose from the ashes of Five Ten's US manufacturing headquarters, all of which relocated to China as part of the brand's assimilation into the Adidas family. Run by longterm Five Ten development and manufacturing associate Sang Lee, along with members of the original design team (who brought you many of Five Ten's most iconic models), Unparallel continues to go from strength to strength in both the rock climbing and mountain biking shoe categories. 

The Rubber

Unparallel use rubbers based on the original Stealth compounds, all of which are sourced from the same factory which has long produced Five Ten's iconic rubber.
