Solestruck is a US company I have been watching for a wee bit. They sell some of the most stunning and outlandish footwear out there so if you have a real thing for shoes, you need to check them out. They offer free shipping to Canada and currently have a nice large sale section as well.
If you really rummage around the sale section you can find some breathtaking sale items. I ran across this Jeffrey Campbell Vicious shoes which set my spike-loving heart all aglow. They were originally $209.95 and if you are among one of the lucky sizes they have left (in the sale colours) then you can get them for just $39.95. I found the shoes still available in a size five (in one colour) and a size six in all the in stock shoes.
If you are a size seven, then take a look at these Senso Prance shoes in Purple Black Leopard. They were originally $209.95 and are now on sale for $49.95. Sizes on the really deeply discounted shoes are very limited so take some time to look around.
Most of the shoes aren't nearly as deeply discounted. These Jennifer Chou Carmelo shoes were $134.95 and are now on sale for $99.95. If you like bright, even neon, statement shoes with a high heel then take a look at these. There are plenty of sizes still available.
This is a US company and though they offer free shipping to Canada, any duties/customs are your responsibility.
