The braces you see advertised here actually are owned by the site owner who hosts my website. I have no connection with them. Having said that, I use ASO ankle braces in my practice. I find them reasonably comfortable and generally accepted by patients. I am not a huge fan personally of the Malleoloc brace, but that doesn't mean it might not work for you. If you do buy one over the Internet, make sure that if it is not for you, it can be returned.
As far as the arch pain with the ASO, you can put an inexpensive insole inside the brace to buffer against the seam. The more adjustability and points of contact a brace has, the more stable I believe it is.
