Thursday Boot CompanyMen's Legend Rugged & Resilient Chelsea Leather Boot

Are these water resistant?

When measured with a Brannock device, my size is 9 1/4 (seriously!). Which would be better? 9 or 9.5?

Are returns free?

I wear 10.5 in work boots so do you recommend size 10 in these boots or get size 10.5 size
