I've never bought shoes from Heel to Toe -- but I have brought shoes in for repair, and I was less than impressed. I had a pair of brown knee-high boots from the 1970s (once belonging to my mother) that required reheeling. $35 later, the boots were reheeled all right, but the shape and size of the heel was nothing like the original (think Faye Dunaway in Network). The new heel was just a big square -- a chunky, oafish block that weighed down the entire silhouette of the boot. They are so ugly now I haven't worn them since.
Another pair of shoes I brought in at the same time needed the lucite heel reattached, and they promptly un-attached after very little wear. I can use Shoe Goo or Superglue too -- I expect something more durable from professionals.
