I severely sprained my ankle a few years back and can't say enough good things about the Shock Doctor ankle brace.
Its super supportive, low profile, and I literally don't know it's on except that my ankle isn't screaming after a ride.
Depends on how heavy duty you want to go. I always wore shockdoctor lace up braces, great support but still comfortable. Slip on ones are less supportive but more comfortable and hard plastic ones are most supportive but can be rather uncomfortable.

Get a Shock Doctor brace. That way you can use whatever 5.10 shoe you want.
Three one linked is what I use and it's absolutely fantastic. Multiple ankle sprains make it a necessity for me.
My orthopedist recommended a pretty special brace which I ignored because it was expensive. So I got this one from Amazon: https://www.amazon.com/gp/product/B005LOSA5M/ref=ppx_yo_dt_b_search_asin_title
I'll go try to find and report back on stretchiness when I find it.
