Z-Tractor Terrain — 01 Front

The design story

Z-Tractor Terrain — an all-terrain rand with gusseted tongue and Bogolan collar trim. Bogolan mudcloth is placed as a considered construction detail, never as surface print, and the aged-gold Z-Closure™ hardware signs the shoe.

Ten rugged utility boots built on deep-lug tread: honest leathers, reinforced rands and Bogolan mudcloth trim at the shaft.

Wearable specs

Z-Grip™ Terrain Cut · ZG-7132

Wheel lock range

14mm

3 collar positions · 4 wheels

Collar travels 14 mm across three detented positions — lock, walk and roll — each held by the carbon-composite pin.

Sole clearance · flush vs drop

  • LockFlush · 9 mm

    Wheels retracted level with the outsole and pinned — pure walking geometry.

  • WalkFlush · 9 mm

    Wheels stay level, brake damper released for a soft glide through toe-off.

  • RollDropped · 23 mm (+14 drop)

    Axles descend 14 mm, lifting the shoe onto free-spinning hubs.

Stack · 30 mm heel / 20 mm forefoot, 10 mm drop

Z-Beam™ lighting modes

Off
Lighting module dormant. The lens reads as a brushed aged-gold inlay at the toe.
Running light
A low ivory running light traces the toe cap — presence, not glare.
Headlight
Twin forward headlights throw a warm beam ahead of the step for night streets.
Turn signal
Amber side pulse at the quarter panel, the pedestrian's indicator.

Laces · twin-tone Bogolan flat tape, obsidian on ivory, aged-gold aglets

Chassis, hubs and heel cell are carried inside the midsole cavity so the shoe still reads as ready-to-wear.

You do
Press the heel collar down until it clicks.
Chassis
Both axles retract into the midsole cavity and the collar pin engages.
Underfoot
A firm, quiet outsole — the shoe behaves as a walking sneaker with no wheel travel.

Wheels fully retracted into the chassis, level with the bottom of the sole. The collar is pinned — the shoe walks like any luxury sneaker.

Story behind the design

The Bogolan story

Fila-ni mudcloth in sapphire & chalk, worked into the crop neck band, left cuff, right cuff.

The cloth

Bogolanfini begins as cotton mudcloth backed with a fine leather skiver so it can take a lace and a lasting pull. It is dyed with a double n'gallama bath with a lime-brightened reserve for the pale ground — the pattern is not printed on, it is drawn in mud and then the ground around it is lifted away. On this piece the mudcloth meets oiled full-grain leather and technical canvas, reinforced rubber rand, woven bogolan mudcloth trim, deep-lug outsole, aged-gold z hardware. z-grip™ terrain cut (zg-7132) on the z-grip™ lugged rubber chassis, raked sawtooth blades set on a 12° forward rake, sculpted almond last with a lifted toe spring, stack 30 mm heel / 20 mm forefoot, 10 mm drop, laced in twin-tone bogolan flat tape, obsidian on ivory, aged-gold aglets, diamond z at the lateral wall, z-vibe at the medial wall.

The motif — Fila-ni

The tape carries paired diagonals folding into one another. In the Bamana reading, Fila-ni is two paths that meet — the House reading of Different Roots, One Human Story. Z-Vibe keeps the motif at heritage scale rather than shrinking it into a logo pattern, so the hand of the maker stays legible on the finished shoe.

Why it sits where it sits

Mudcloth is placed on construction points, never scattered as decoration: crop neck band, left cuff, right cuff, front placket. These are the lines the eye already follows on this silhouette, so the cloth reads as structure — an edge, a facing, a seam — and holds its meaning at three metres and at arm's length alike.

The hand-work

Each length is block-matched panel to panel — the atelier discards any length where the repeat cannot be aligned. Tape width and motif repeat are cut to the size band, so a petite run and an extended run carry the same proportion rather than the same measurement.

Global Heritage Fusion™

African heritage, global luxury, future design: the mudcloth is set against European finishing and the aged-gold Z-Closure™ mark. Nothing is erased on either side — the meeting is the design. Different Roots. One Human Story.

Care · Air the piece after wear and store folded with the tape inside. Steam from the reverse — a hot iron directly on the mudcloth flattens the weave.

Refinement provenance

Z-Studio refined · 1/7 views shot

Each step below reflects work that actually exists for this piece. Refinement is a design process — it does not imply the piece is production-released.

  1. Owner-approved design board intakeComplete

    The signed design board was registered as the source of truth; silhouette, Bogolan placement and hardware were locked from it.

  2. Z-Sole Architecture™ assignmentComplete

    Sole identity resolved for this style — Z-Grip™ Terrain Cut (ZG-7132) on the Z-Grip™ lugged rubber chassis, raked sawtooth blades set on a 12° forward rake, sculpted almond last with a lifted toe spring, stack 30 mm heel / 20 mm forefoot, 10 mm drop, laced in twin-tone Bogolan flat tape, obsidian on ivory, aged-gold aglets, diamond Z at the lateral wall, Z-VIBE at the medial wall. Tread, last and stack height were made unique to the shoe rather than shared across the register.

  3. Bogolan signature verificationComplete

    Mudcloth was confirmed as a construction detail (laces, panel, tongue or heel band) and not surface print, and the aged-gold Z-Closure™ mark was placed.

  4. Z-Glide™ wheel & Z-Beam™ lighting integrationComplete

    The retractable wheel housing and lock/unlock travel were fitted into the sole stack, with the forward beam module set into the toe box.

  5. Z-Studio 4K refinement passComplete

    Studio refinement rebuilt the shoe at 4K: cleaner last geometry, corrected proportions and true material rendering on the released angles.

  6. Seven-view studio captureIn progress

    1 of 7 angles are distinct photographs; 02 Left, 03 Right, 04 Back, 05 Interior, 06 Inner tags, 07 Fabric detail still read the design board.
