From Victorian era curiosities to early 20th century equestrian and motorcycle wear to rare WW2 era items - Black Sign garments are beautifully constructed, with a shared identity and aesthetic cohesion running through the collection to a degree we rarely see in brands focusing on reproductions & recreations.

For this exclusive collaboration, they've partnered with Clinch Boots. Clinch is made by BRASS, one of the first high-end shoe repair shops to open in Japan, owned and operated by Minoru Matsuura. Starting with simple shoe repairs, they quickly branched out - developing their own custom lasts and rebuilding vintage footwear, before eventually developing their own in-house line.

The meeting of their minds has resulted in the most impressive boots we've ever seen: the Transcontinental Boots. Standing at an average of 16" tall (the height will change slightly relative to the size of the shoe), these pack an impressive 6 eyelets, 9 speed hooks, another 5 eyelets, and two custom brass buckles to keep them securely on your legs. Brown O'Sullivan cork outsoles and heels provide fantastic grip and comfort, while still cutting a clean, low profile.

The leather is black waxed Gustave cowhide, from the Degermann tannery in France. Degermann is France's oldest leather tannery, with a history going back over 300 years. The hides are combination tanned - combination tanned leathers are finished with both natural vegetable tannins and mineral ones, resulting in a leather with the durability of a veg tan and the softness of a chrome tan. After tanning, the leather is coated with a natural wax, which is heat pressed into the hides, giving additional durability and water-resistance.

This collaboration is highly limited, and will not be restocked.

We reference Brannock sizing for our footwear. The Brannock Device is the standard foot measuring tool for the world's footwear industry. Most better quality footwear stores will have one.

If you have any questions about sizing, or are unsure of your size, please contact us before ordering.

Our sizing recommendations


The CN WIDE last is between D and E width. It fits very snugly from the waist to heel, with a low instep. We have found that most people are able to wear different sizes in this last, depending on if they prefer a snugger fit or a roomier fit.
  • Narrow and low volume feet:
    • 0.5 size smaller thanBrannock for a snug fit
    • Same size as Brannock for a more relaxed fit (you may need to use insoles, thick socks, or both)
  • D-Width and average volume feet:
    • 0.5 size smaller than Brannock for a snug fit
    • Same size as Brannock for a more relaxed fit (you may need to use insoles, thick socks, or both)
  • E width feet with average volume:
    • Same size as Brannock for a snug fit
    • 0.5 size larger than Brannock for a more relaxed fit

We suggest the Protalus T-75 or Protalus M-75 insoles and Darn Tough Full Cushion Socks.
