I recently ordered these boots from Piperlime for 49.99:
http://www.dsw.com/shoe/restricted+mari ... dId=211196These boots are not of the best quality, but for that price, I wouldn't mind getting it for just one season.
I think the shoe area is about a 1/2 size too big. I wear a 5.5 and its still a little roomy, but an insert will fix all that.
The calf area has three buckles which are all adjustable. When adjusted at the tightest, it has slightly loose fit around my calves when I wear thick thigh socks. My calves are just over 12" around. This is probably the closest fitting calf boot I've tried on that are not Duo or stretchy boots.
They do tend to slouch after wearing it for an hour around the house, probably because its not tight enough around my calves.
The back of the boot does go up pretty high, about 16.5 inches. It does come about quarter way into the back of my knee, but because the boot is so soft, I don't find that to be bothersome.
I think this boot would be a good fit for someone whose calves are maybe at 12.5'-13" around if you intend on wearing socks or leggings.
I'm not sure if I'm going to keep or return this pair...it's the closest fitting boot I've found at such a low price.
