Mapski,
I wouldn't skip running on the hard surface altogether, but you may want to use a lace up brace (as suggested in the last post) on the days you are playing on harder or uneven surfaces to help prevent another ankle sprain.
It seems like the neoprene ankle brace has been working well for you in the past year, but these braces and elastic pull on ankle braces will only add a little support and will not prevent ankle sprains.
The lace-up ankle braces are a good compromise between the neoprene ankle braces and the heavy-duty ankle braces. The key is to find one that is comfortable for you, that you would be willing to wear while you are playing sports. Look for one with some elastic in the heel area and without struts on the side, you might find this more comfortable. Have fun.
