Sidi shoes

I'd say buy the discounted ones now before they run out, and return yours for a refund.
But...
"Returned goods must be unused, in a saleable condition in their original packaging with all labels etc still attached. Once we receive the goods and completed returns form we will refund you, by the method you used to pay for your order."

Well.......I returned some Dominators to Chain Reaction Cycles after I had used them for one ride as they were slightly too small, they weren't in perfect condition anymore as I had fitted the cleats and taken a few steps on concrete. They refunded the monies no problem.
I think for big retailers its a big hassle to send the items back to the customers, and in the age of internet forums etc (especially with bikes) pissing a small minority of customers off isn't worth it if they decide to kick up a stink online.

So anyway, I reckon clean them up and send them back, and buy the discounted ones. If they don't refund you then send the new ones back.

How much were the originals bought for?
