My wife and I recently visited Washington D.C. We planned on walking everywhere. After 3 miles in my old tennis shoes, I had a blister on one heel and a sore ball on the other. We arrived at Comfort One Shoes on 7th st. and after announcing my desperation to sales person, Jenisa, she promptly put me into a pair of clouds. I have never paid so much for a pair of shoes, yet I would gladly do it again. We had planned to take a cab 2.5 miles back to the hotel, but these shoes gave me the confidence and comfort to make that trek, plus another 7 miles the next day. I am a complete convert.
