Z-Step Cloudline Ivory — 01 Front

The design story

Z-Step Cloudline Ivory — an ivory knit-and-leather step sole with a mudcloth heel counter. The Z-Glide Wheel System™ is fitted: lock the wheels flush with the sole to walk, or deploy them below the sole to roll, with Z-Beam™ lighting at the toe. Bogolan mudcloth is placed as a considered construction detail, never as surface print, and the aged-gold Z-Closure™ hardware signs the shoe.

Five terraced-sole house shoes from the approved Z-Step™ board. The stepped midsole hides the Z-Glide™ chassis — lock the wheels flush to walk, deploy them to roll, and light the step with Z-Beam™.

Wearable specs

Z-Air™ Ivory Cut · ZA-6875

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 · 6 mm

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

  • WalkFlush · 6 mm

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

  • RollDropped · 20 mm (+14 drop)

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

Stack · 40 mm heel / 26 mm forefoot, 14 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 · flat woven Bogolan mudcloth tape, aged-gold aglets

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

Z-Glide Wheel System™

4 wheels · lockable · Z-Beam™

Twin retractable axles, forefoot and heel, recessed into the midsole cavity.

Step 1 · Lock

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 clay & bone, worked into the crop neck band, left cuff, right cuff.

  • crop neck band
  • left cuff

  • front placket

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 n'tjankara leaf mordant followed by a slow black-mud pass — 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 house leather and knit upper on a sculpted terraced midsole, woven bogolan mudcloth construction panel, bogolan mudcloth lacing, z-glide™ retractable wheel chassis with lock / walk / roll collar, z-beam™ toe lighting module, aged-gold z-closure™ hardware. z-air™ ivory cut (za-6875) on the z-air™ cushioned eva chassis, banded terrace steps rising from forefoot to heel, high-walled bootie last with a wrapped ankle cradle, stack 40 mm heel / 26 mm forefoot, 14 mm drop, laced in flat woven bogolan mudcloth tape, 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 bias-cut for the curved runs, hand-basted before the topstitch so the motif never breaks at a seam. 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 · Cold hand-wash or specialist clean only. Mud dye deepens with age; never bleach, and dry flat away from direct sun.

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-Air™ Ivory Cut (ZA-6875) on the Z-Air™ cushioned EVA chassis, banded terrace steps rising from forefoot to heel, high-walled bootie last with a wrapped ankle cradle, stack 40 mm heel / 26 mm forefoot, 14 mm drop, laced in flat woven Bogolan mudcloth tape, 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.

    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.
