I echo dharmagirl’s disbelief that you were shoe shopping in Oceanside!! nordstrom.com or piperlime.com would be MUCH better choices, and you wouldn’t get lost! I just picked up two pairs from nordstrom.com myself. . .
As for the GPS, my husband also has a Garmin personal one that he uses for running, and he LOVES it. The only caveat I would add is to keep your receipt, as his failed unexpectedly, but the company’s customer service was excellent, and they immediately replaced it.
