Favorite shoes are too important to toss away at the first sign of trouble, and the pros at Cobbler's Corner have managed to rebuild plenty of seemingly exhausted footwear. Plus, the prices are reasonable and the repair work is friendly and speedy; in many cases, new heels can be put on while you wait. And although Cobbler's Corner can also be found in Greenwood Village and the Cherry Knolls Shopping Center, we're partial to the one on 17th Street. Downtown used to be full of hardworking small businesses; it's good for the sole to know this one is still around.
