These are my first pair of EMU Australia Women's Bronte Hi Boot, actually my first pair of shearling boots ever. I normally wear a 7 1/2-8 and got the 8 because even though I read the reviews that said they run big, the size 8's cost about $40 less than the 7's. These are very comfortable, even barefoot, and the wool is not itchy at all.  There is no arch support but so far, it feels fine. As I have noted in other reviews about boots for me, I have big calves, and therefore can't pull these up all the way, so they are scrunched a bit. Not uncomfortable, just annoying. I can't tuck my jeans inside so I ended up rolling up my jeans. Maybe these will work with leggings or tights. I like these boots so far, but couldn't see spending full price on these. Also, a good idea to spray them with suede waterproofing spray, which I didn't yet because I was too excited to wear these! Bottom line: super comfy, order a size down, the shaft won't fit so well if you have larger calves and get these when they are on sale!
