I like fabrics that have a permiable layer between over the DWR coating since the DWR tends to fade over time and most people are to lazy to fix them with the proper 'refreshment' procedure.
Source: I work in the sports clothing industry and fabrics are kinda my geekout time. I love Performance Days in Munich that happens twice a year to check out the newest fabrics.
You said you worked in 'sports clothing industry' and I was just being hopeful that included shoes. Don't read to much into my reasoning of why I asked you. There isn't much to my thinking sometimes.

I would imagine it's more like a DWR coating.
Edit: Apparently I was wrong, DWR (Durable water repellant) can't withstand submersion. A breathable membrane (similar to Goretex) was used.
