Where can I find cheap SILVER UGGS? Or silver UGG lookalikes?

I have this really cute red dress with some silver bands around the straps and I have everything to go with it except shoes! It's a shorter dress and I was planning on wearing it to this date in the wintertime and I really don't feel like wearing heels. I saw some silver UGGS online but I can't afford them at the retail price. If you know of anywhere to find real silver UGGS or lookalikes for under or around $50 please let me know! I'm a size 8 btw.
