Breathable Waterproof Trainers for Yacht Deck Crew

I'm looking for a specialized footwear solution for deck crew on yachts. The trainers must be both waterproof and breathable, designed to withstand the rigors of cleaning, maintenance, and navigating the yacht.

Key requirements:
- Waterproofing via seam-sealed construction
- Breathability primarily through breathable mesh
- Durable and suitable for marine environment
- fully waterproof and breathable
- flexible for movements of boat and moving around
- great grip that does not cause marks on deck
- smart but casual look.

Ideal Skills and Experience:
- Experience in designing or manufacturing waterproof, breathable footwear
- Knowledge of marine equipment and needs
- Strong background in materials science or textile engineering
- ECO TEXTILES WOULD BE AMAZING

Please provide examples of previous work.
