Early-stage concepts in fit, protection and visibility. Unvalidated, built to start the conversation.

Fit & performance

Snowboard Boot Pump Technology

Concept

An inflation-based fit system for snowboard boots, a pump that lets riders dial in heel hold and pressure on the hill to protect the ankle.

01The problem

Heel lift and ankle instability during aggressive riding. Ankle injuries are among the most common in snowboarding, and a constant concern for riders.

Yet the industry's focus has shifted to convenience: quick-entry systems like Step On and Fase make getting in easier, while support and protection have barely moved. This concept puts safety back at the centre.

02Observation

Traditional closure systems distribute pressure around the boot but don’t dynamically respond to the rider.

04Concept

An integrated pneumatic system allowing localised pressure adjustment.

05Prototype

Not built yet: making a physical prototype needs the means, materials and workshop a brand can provide. The image below is an AI render showing how it could look.

06Test

Proper testing needs a full lab: pressure mapping, cold-chamber cycles and on-snow validation inside a real boot. This is the step I want to take with a brand.

07Next iteration
  • •Reduce pump volume
  • •Improve bladder integration into the liner
  • •Validate pressure distribution on the heel and ankle

If you like the idea, let’s take steps 06 and 07 forward together.

Footwear

Boat Shoe Skate

Concept

A boat shoe reworked as a skate silhouette: moc-toe construction and rawhide lacing on a vulcanised cupsole, all-black suede with a gold hardware detail.

01Insight

Boat shoes and skate shoes already share a lot: suede uppers and flat, grippy soles. What if a deck shoe could take an ollie?

  • Board feelVulcanised sole, thin and flexible
  • Grip-tape abrasionThick suede that survives the ollie side
  • Ollie zoneReinforced moc toe where the board rubs
02Mood

I’ve been in boat shoes since 1988. Wooden sailboats, lake water and hand-stitched rawhide: quiet, crafted, a little nautical, then dropped into skate culture.

03Ideation

Line drawings to find the silhouette: low and mid heights, the moc-toe line, eyelet spacing and where the S hardware sits on the heel.

Outerwear innovation

Outerwear concepts

Concept

Thermal Sensory Jacket

A jacket that tracks body temperature and flags it on the garment when it drops too low, a clear signal that it is time to head inside. Built mainly for kids, so parents can read the warning at a glance instead of guessing, and know when to call the hot chocolate break.

Impact-Air Ski Jacket

Protection built into the shell rather than strapped under it. A pneumatic membrane draws air in as you ride and loads the armour zones at chest, spine and shoulders. On impact that trapped air becomes a cushion, then bleeds out through controlled release valves so nothing bursts and the system stays intact for the next run.

Adaptive-Chameleon Outdoor Jacket

A shell that reads the weather and changes how it is seen. On bluebird days a chrome micro-line structure turns the surface bright and reflective. When the forecast closes in, a phosphor-active layer takes over and the jacket reads fluorescent: maximum visibility exactly when the light goes flat. Ideal for spotting people in the backcountry, and for getting a better shot of them.
