Someone's already posted a youtube link, but I'd search for 'AthleanX ankle injury' - When I did my ankle in 2 years ago I used some of their suggestions to speed up recovery and increase strength. I also got on the bike to maintain some level of aerobic fitness. I started jogging after a few weeks, got around the Northern XC champs (not very quickly but minimal discomfort) at 4 weeks, and was racing properly with no discomfort (albeit not at peak physical shape) at 8 weeks (National XC).
Every morning when I brush my teeth I do 1 minute eyes shut balance on each foot. Wobble cushions can also help. Working different bits of the foot with a theraband can also be good. As is mobility.
As for shoes - I'd be more interested in the material of the upper than the drop. When I did my ankle (I was racing and it was my first ankle injury in 10+ years), I was wearing VJ iRoc, which are quite rigid around the ankle and have no give. Normally I'd wear Inov8 Xtalons, which are a bit softer around the ankle so give a bit. The thinking (also discussed by someone who's used both shoes) is that, if you go over in the Xtalons, the give means your foot can react a bit more and the force dissipate a bit more through the shoe, minimising injury; whereas in the VJ there's nowhere for the force to go, so it goes straight into your ankle. This is the thoughts from an N of 2 though.
