I am a 54 year old female who walks a lot, I wear proper,professionally fitted walking shoes, but every now and again my ankle gives way when I am walking. Yesterday this resulted in a fairly serious fall onto the bitumen, resulting in a black eye,bruised lip, and various other deep cuts to my face. My question is, is there anything I can use to prevent my ankle from doing this again? I had thought of hiking boots, but most of them are very heavy and cumbersome. Would an elastic ankle support help?
