Every material chosen the same way: would a craftsperson who takes pride in their work use this? If not, it's not in your shoe.
Year-round upper

Vegetable-tanned leather.
Vegetable tanning is the oldest method of leather preparation — and the best. It uses natural tannins from bark and plants instead of chromium salts. The result is a leather that molds to your foot over time, develops a rich patina, and lasts decades rather than seasons.
It costs more to make. It takes longer to produce. It's the only kind we use.
Ages beautifully
No chrome tanning
Molds to your foot
Breathable
Biodegradable
Material note
Veg-tan leather will lighten or darken slightly depending on your climate and how you wear it. This is the leather working — not a flaw. Every pair will age differently, and yours will be unlike anyone else's.
Year-round upper
Suede
Upper · Suede
Vegetable-tanned suede.
The same vegetable-tanned origin as our leather — split and napped to create a soft, brushed finish. Suede carries the warmth and character of full-grain leather with a quieter, more tactile surface.
It reads differently in every light. Worn in, it becomes something you can't replicate in a factory.
Soft hand feel
No chrome tanning
Warm texture
Natural patina
Material note
Suede is more sensitive to water and abrasion than full-grain leather. We recommend a natural suede protector spray before first wear. With basic care, it develops a character that only improves.
Year-round upper · Vegan
Apple
Upper · Bio Vegan
Apple leather. Waste, made beautiful.
Apple leather is made from the cores and peels left over from the juice and food industry — material that would otherwise be discarded. The pulp is dried, ground, and bonded with a natural binder to create a durable, supple upper material with a surface finish remarkably close to full-grain leather.
No animal. No petroleum. No compromise on quality. It's the right choice for anyone who wants a leather-look shoe built entirely from what already existed.
100% vegan
Fruit waste origin
No petroleum
Leather-like finish
Year-round
Biodegradable base
Material note
Because apple leather is an agricultural byproduct, there is natural variation in tone and surface texture between batches. No two pairs will be identical. We consider this part of the material's character — not a quality issue.
Summer upper
Hemp
Upper · Summer
Fishbone hemp weave.
The fishbone weave is a traditional textile structure — two sets of yarns interlocked at opposing diagonals, creating a herringbone-like pattern that is as visually striking as it is structurally sound. It gives the fabric natural stretch resistance and even airflow across the surface.
The material is 100% hemp. Hemp is three times stronger than cotton, naturally antimicrobial, and gets softer with every wear. This particular weave is the kind of fabric that makes people ask what it is.

Material note
Hemp softens noticeably after the first few wears as the fibres settle. The fishbone pattern becomes more defined as it breaks in. This is the fabric doing what it's supposed to — it's at its best after a few months of use.
Winter upper
Wool
Upper · Winter
Knitted wool outer.
Not boiled. Not felted. Knitted — a structured textile construction that gives the shoe warmth without weight, and a refined surface finish that reads nothing like athletic knitwear.
Wool regulates temperature naturally, wicks moisture, and resists odour. The knit structure allows the upper to move with your foot rather than against it — which matters more in a custom shoe than in anything else.

Material note
Knitted wool can pill lightly in high-friction areas during the first few weeks. This settles with wear and does not affect performance or durability. Spot-clean only — do not machine wash.
Your lining. Your call.
The inside of the shoe is yours to configure. Not an afterthought — a choice. We offer three options depending on the season, your climate, and how your feet run.
Winter · Cold climates
Wool lining
Warm, soft, and naturally temperature-regulating. The right choice for cold months or anyone whose feet run cold. Pairs especially well with the knitted wool outer.
Year-round
Leather lining
The classic choice. Soft vegetable-tanned leather against the foot — breathable, durable, and it only gets better with wear. The standard for year-round use.
Summer · Warm climates
No lining
Maximum breathability. If you're pairing with the hemp upper or run warm, removing the lining entirely lets the material speak for itself — and keeps things as minimal as possible.
Outsole
Rubber. Full stop.
Natural rubber outsole. No TPU. No plastic compounds. Rubber grips, flexes, and wears honestly — you can see how a rubber sole ages, which means you can trust it. Nothing hidden in the compound.

Midsole · Your choice
Bio-EVA. At the thickness you want.
Bio-EVA is a plant-derived alternative to petroleum-based foam — same cushioning performance, none of the synthetic origin. Choose your stack height: more sole between you and the ground, or less. Both zero-drop. Both flat.

Every material chosen once. For the right reason.
We don't use vegetable-tanned leather because it's a marketing word. We use it because chromium-tanned leather is worse for the person wearing it, worse for the people making it, and worse at the one job leather is supposed to do — get better over time.
Same logic applies to everything in this shoe. Bio-EVA instead of petroleum foam. Rubber instead of TPU. Hemp and wool instead of synthetic uppers. None of it is a compromise. All of it is a decision.
