The Unparallel Regulus is a stiff, downturned climbing shoe, providing absolute precision on any angle and all styles of climbing, yet best suited to steep terrain.

Based on the Five Ten Hiangle, you will find familiar traits running throughout the Unparallel Regulus shoe, such as the general aesthetics and most importantly the fit. The upper is made from an unlined synthetic suede, which provides a soft feel while maintaining a perfectly snug and secure fit. On the base of the shoe is a full length Unparallel RH (Real Honour) rubber sole, which competes blow for blow with the best rubbers in the business. This is the harder of Unparallel's two climbing compounds, and is better suited to micro edging than the RH formula. This means, whilst offering precision grip on small protrusions, it is a little less sticky overall. On the upside it does last longer than its RS counterpart. The midsole is the stiffest in the range, making it awesome on micro edges and moves where the shoe/rubber needs to hold its shape. Finally, a highly tensioned heel and sling shot rand locks your foot into the shoe, providing extra power and bombproof heel hooks.

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.

    Great Shoe

    My street size is a large UK12 and I got these in a 12. They're a really tight, bunched up fit (to the point that I was worried that I'd gone too small at first) but they're surprisingly comfy. They take some practise to get into but once you're in they feel like a super sticky pair of socks. Your feet are knuckled up and ready to go but there are no uncomfortable pressure points or rubbing. Effortless grip on steep stuff, toe and heel hooks are a dream, a little soft around the toes on small slabby stuff (especially when you way 14 stone) but they make up for it by being nice and sticky
