yes another question about sizing and such.. I"m sorry!! There isn't anything in past posts about this.
i want these amazing boots:

1. i'm not sure if I'm looking at the right size. I know generally baby does M 23-23.5 in boots. I normally buy 23.5, would it be smarter to get a L or will the M fit me? Just for other references I wear a 6-7 US in shoes depending on the heel and make. My feet measure 23cm exactly but i like a little space in the shoes to breathe.
2. also do they have a zipper? how to they do up?
