I noticed that too, they do look new. There seems to be a bit of a blonder new look Avril emerging in there, cardigans & jeans, nice.
There is a web/chat/forum site I think its called mildsauce.net which goes on about topics related to Avril and her feet. You want to read them. Some of the guys on there have a fetish about her in flop flops, no thanks. Pleanty of the chucks & sweaty socks please..
