polar fleece socks for the new rubber boots

I found these rubber boots Sunday and I wanted heavy socks for them
I made the socks with left over polar fleece

the pattern is at the following link

I added 2" to the top of the sock top pattern
since I'm planning for these socks to be used in the rubber boots
