tx - I think it means "not a boot". It is a slip-on and the "upper" does come up high on the bridge of the foot. There is elastic fabric all around the top of the shoe. I couldn't tell you how it would hit your ankles. You could purchase from a vendor on Amazon that has free returns if you wanted to give these a try. I have problems with the areas below the ankle spreading into the arch and to the top of the bridge and these feel fine for me. Sounds like your issues are different though.
