Why worry?

ok ok thank you all for your comments.. If you have never seen Keens they are more like a shoe than a sandal and do have great foot support but my keens do not have ankle support.. that said unless i am doing a really rocky hike that is generally not a problem. I did not know what the trail was like so the reason for asking. My H has a pair as well but his are beige mine are black .. on a muddy trail he may do better with his hiking shoes as the mud won't show on the black as much:)
These are the shoes I have in black.. I wear them with a tennis sock so you dont really see the sock and keeps my foot from getting muddy. http://www.keenfootwear.com/us/en/product/shoes/women/outdoor/newport/shitake!baroque%20rose%20(tumbled)
as you can see they are much more supportive that what one might imagine a sandal to be:)
