Scott,

I bought a pair of Simms Vapor boots, the crossover hiking/wading boots, a few months ago. I normally wear a size 9 athletic shoe and bought these boots in a size 9. I wear a light-medium pair of socks and neoprene guard socks in the boots and they fit perfectly. They also fit well with regular stocking foot waders and the medium weight socks and keep me comfortable in 45-50 degree water.

So, for cold water use, I think I would only go up one size. I assume that the boot I have is sized the same as the Freestone.

Regards,
Ted
