Ahoy Captain Cronus!
Good boots can sometimes pop out of the woodwork if ye know where t' be lookin'. Rummage Sales, Garage Sales, or even second hand stores may fetch ye the perfect pair. Be sure to consider what an old boot would look like with the top o' 'em bucketed over.
Myself I found the perfect size, true leather ladies boots passin' by a sale, way back in a corner o' the Pike Place Market, for just 3 American Dollars. Yhar... a pyrate lass loves a deal, she does.
If you're not the searchin' an' Rumaging type, try http://www.renboots.com/

Good Plunderin'!
