I bought a pair of Vessi Weekends last year. Personally, I find them very comfortable but the outsole isn't durable enough for me.
I walk about 50km per week and there was basically no tread left in the outsole in less than 6 months. The rest of the shoe is fine though and still waterproof. I'd consider getting another pair of Vessis if they had a version with a more durable outsole.
