I find walking is a good form of exercise as well as a great way to get from point A to point B. Wearing comfy shoes is a simple way to ensure that you incorporate walking into your everyday activities. I have been on the hunt for shoes that are great for walking and are cute too. I found these Erin Ballet Flats ($90) by Keen and have been wearing them about town, running errands, and chasing my girls at the park.

More fashionable than sneakers and just a little less comfy than running shoes, these flats were made for walking. The soles are made from eco-friendly materials; the inner sole contains renewable cork for cushioning, and the lightweight polyurethane outsoles are made with no environmentally harmful adhesives.

The lining is made of wicking materials in case your feet get a little sweaty when you're on the go. You can pull insoles out of these Keens quite easily and slip in your own customized orthotics if your feet need personalized support. The mesh detail on the upper part of the shoes allows the foot to breathe and creates room for bunions, a bony bulge by the base of the big toe that can make shoe shopping a bear.

If you're looking for a casual, walkable, sustainable shoe, you can buy the Erin Ballerina flat directly from Keen. The manufacturer feels that this shoe runs true to size and I found that it ran a little big, so order wisely.
