Beware of sizing. I would like to offer the following advice if that's ok, from my experience you should always go for a size bigger than you normally take.
Sendra Cowboy Boots. These come up really small. I'm a 5/12 and have just bought a new pair of (Frye types) and they are a size 7!!! The tops feel tight but they give beautifully in no time at all. So go for a size or size & a half bigger. I bought THE most gorgeous pair of Sendra Cuban Heeled boots from another ebayer, they are a 5/12 are are a nice fit.
Loblan. Ahhhh another wonderful boot. I bought a fab. pair from another ebayer which are size 6 (lovely and roomy) mine are also nice and wide on the foot.
I love my boots so much I often want to take them to bed with me but my little dog won't allow it.
