Black Diamond Circuit notable features

-The Black Diamond Circuit blurs the line between lifestyle sneakers and performance-oriented approach-centric kicks. Its knit construction underscores a breathable kind of comfort.

-It is among BD’s most versatile hikers. Case in point: It comes with a collapsible heel, which transforms the shoe into a slip-on.

-The Circuit comes with a molded midsole and a brand-exclusive outsole, called BlackLabel-Street. Together, these two underfoot components deliver a cushioned and secure ride across rocky trails.

Size and fit

Black Diamond’s Circuit is a low-cut approach shoe engineered for both men and women. Fit customization and lockdown security come by means of the shoe’s lace-up closure.


The Circuit from Black Diamond promises to provide ample slip resistance over different types of surfaces with its BlackLabel-Street outsole. Diamond-shaped low-profile lugs are scatted all around it to help adventurers remain surefooted over tricky terrain. The smooth and lug-less construction of its front end (also known as climbing zone) offers additional sticking power on edges.


The BD Circuit comes with a hard-wearing molded midsole for sufficient terrain stability and comfort underfoot. It is made of EVA or ethylene-vinyl acetate, which means it can withstand a great deal of weight and stress, even with repeated use. It owes its ability to absorb and mitigate shock to its chunky yet springy construction. To improve its comfiness, Black Diamond engineers paired it with a cushy footbed.


Premium knit fabric is the primary material used in the Black Diamond Circuit’s low-top upper. Both its mesh tongue and collapsible heel come with synthetic pull tabs to make getting in and out of the shoe that much quicker.

A heavy-duty rand, which is made of rubber, covers a good portion of the Circuit’s forefoot region, delivering adequate abrasion protection and light climbing grip at the same time. The shoe’s heel also has a similar coating for extra rearfoot support.

What rounds out all things upper in the Black Diamond Circuit is the hiker’s lockdown system. It consists of six pairs of plated eyelets and a hard-wearing lace made of interwoven synthetic cords.

Nice to know

-Approach hikers who are looking to pair the Circuit with a knit climbing shoe from the same brand might want to give the Black Diamond Momentum a try. La Sportiva also has a knit offering in the TX2.

-The Circuit is one of the first-ever approach shoes Black Diamond has released.
