For a golfer, the ankle brace used may be a matter of convenience for donning, cost, fit in the shoe, etc. rather than based on performance to stabilize the ankle. I think many of the research studies look at stabilization, speed, vertical leap, and so forth. Although a brace that performs best for more active sports like soccer, basketball, and football may be a good brace for everyone, there may be a brace that is less expensive that will be OK for a golfer.
In general, you shold probably look for a lace-up brace and probably with some sort of velcro straps. There are many names that are probably similar in quality - ASO, Swedo, Active Ankle, Air Cast, Rocket Sock and others.
The "cadillac" of ankle braces is the ASO. It mimics an ankle tape job, is comfortable, low profile and will last a full rigorous sports season. For golf, it should last several years and should fit comfortably in a golf shoe. Most professional athletes choose this brace and you can get them for under $50. We carry them in our sports medicine store and it's our most popular item. http://www.basportsmedicine.com/prodinfo.asp?number=MS%2D2640
