I bought mine in summer 2005 and I remember there was that red, I wanted them but only green were left with my size! Price in Italy is now 245 euro, they are great quality shoes and 100% made in Italy! I hope it helps.
They're definitely Sigerson Morrison. I recently read an article that said Reese is a HUGE fan and recently went in their store and ordered 6 pairs of their flats in all colors. She has also been seen in their gladiator sandals.
I think they're an "older" model of Belle by Sigerson Morrison's--probably from last fall since they look to be suede or nubuck. The current season flats are all in patent leather.
