Z-Rail Metro — Z-Rail™

The design story

Z-Rail Metro — a metro low rail sole with a commuter-grade grip pad and Bogolan tongue tile. Bogolan mudcloth is placed as a considered construction detail, never as surface print, and the aged-gold Z-Closure™ hardware signs the shoe.

Ten rail-form sole architectures: continuous track midsoles, sculpted sidewalls and one Bogolan mudcloth reveal on each pair.

Materials & craft

Upper: Engineered mesh and nubuck upper, rail-form track midsole, sculpted sidewall, woven Bogolan mudcloth detail, aged-gold Z-Closure™ hardware. Z-Glide™ Metro Cut (ZG-8092) on the Z-Glide™ retractable wheel chassis, raked sawtooth blades set on a 12° forward rake, squared architectural last with a chiselled toe box, stack 40 mm heel / 26 mm forefoot, 14 mm drop, laced in round braided Bogolan cord over a waxed core, aged-gold aglets, diamond Z at the lateral wall, Z-VIBE at the medial wall

Heritage: Hand-printed Bogolan mudcloth facing, round braided Bogolan cord over a waxed core, aged-gold aglets — Global Heritage Fusion™.

Fit guidance

True to size. Half size up if you wear a thick sock or prefer extra toe room.

Width: Standard D width, generous forefoot volume.
Last: squared architectural last with a chiselled toe box
Stack: 40 mm heel / 26 mm forefoot, 14 mm drop
Break-in: Wearable straight from the box.
Socks: Sized over a standard performance sock.
Lacing: round braided Bogolan cord over a waxed core, aged-gold aglets Re-lace from the throat up for a locked midfoot.
Z-Glide™ wheels: Fit is measured with the wheels retracted flush to the sole. Deployed, the stack rises a few millimetres — no size change required.

Wearable specs

Z-Glide™ Metro Cut · ZG-8092

Wheel lock range

14mm

3 collar positions · 2 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 · 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 · round braided Bogolan cord over a waxed core, aged-gold aglets

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

Z-Sole Architecture™

Z-Glide™ Metro Cutunit ZG-8092

Cut for this style alone — no other shoe in the house carries this sole.

Chassis: Z-Glide™ retractable wheel — walk, glide and roll from one collar
Tread cut: raked sawtooth blades set on a 12° forward rake
Last: squared architectural last with a chiselled toe box
Stack: 40 mm heel / 26 mm forefoot, 14 mm drop
Laces: round braided Bogolan cord over a waxed core, aged-gold aglets
Side signature: Diamond Z medallion, aged gold, set into the lateral wall. Z-VIBE wordmark, tonal debossed, along the medial wall.

Step 1 of 3

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.

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 engineered mesh and nubuck upper, rail-form track midsole, sculpted sidewall, woven bogolan mudcloth detail, aged-gold z-closure™ hardware. z-glide™ metro cut (zg-8092) on the z-glide™ retractable wheel chassis, raked sawtooth blades set on a 12° forward rake, squared architectural last with a chiselled toe box, stack 40 mm heel / 26 mm forefoot, 14 mm drop, laced in round braided bogolan cord over a waxed core, 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 hand-turned and pick-stitched in silk thread, then pressed over a ham so the tape sits flat, not glued. 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

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.

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.
Z-Sole Architecture™ assignmentComplete
Sole identity resolved for this style — Z-Glide™ Metro Cut (ZG-8092) on the Z-Glide™ retractable wheel chassis, raked sawtooth blades set on a 12° forward rake, squared architectural last with a chiselled toe box, stack 40 mm heel / 26 mm forefoot, 14 mm drop, laced in round braided Bogolan cord over a waxed core, 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.
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.
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.
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.
