if you're really worried about ankle support, you should get a pair of hiking poles (they look like ski poles). it's amazing how much extra support the poles give you.
i forgot to mention earlier, if you want full-on summer shoes for hiking try the Keen sandals. clock and i have put a TON of miles on our shoes (on trail and off) and they're just awesome. when i was pregnant and none of my shoes fit me any more, i got a pair of Keen mary-janes that worked for fat feet. they were the ONLY shoes I wore from my 4th month on, and i didn't have ANY foot problems while pregnant (other than terrible fluid retention); remember, I put on 60 pounds!
a few years ago i got tendonitis in my foot so i take shoes seriously. i have 4 pair of Docs (2 mary-jane, 2 boots) i wear in non-summer weather, Merrells for sport shoes, Merrells for hiking, and Keen sandals for hiking & daily wear. all of my dress shoes have low chunky heels. Foot injuries suck!
in conclusion, go to REI and tell them what you want to do and let them fit you for shoes.[ Parent ]
