Skechers Shape-Ups have been all over - TV commercials, Internet, Facebook and Twitter. They have many celebrity endorsements and do a decent job doing PR and Marketing for the product.

The Facebook page could definitely have more followers - considering most people in America have heard the Shape-Ups. However, they do a good job of marketing to celebrities and showing that they are "In-Style."

Skechers does a pretty good job keeping up with their twitter - they tweet PROMO codes, giveaways, and celebrities wearing the product.
Certain endorses - i.e. celebrities - is a great way to for consumers to hear about product. Celebrities like Kim Kardahsian has 6 million followers on twitter - and just one tweet about Skechers Shape-Ups can reach that many more people.

On YouTube there are different types of Skechers Shape-Ups videos. There are reviews, instructions, and commercials. This 15-second SuperBowl ad was viewed by over 500,000 people - just on YouTube plus all of the SuperBowl viewers. I would say their commercials and ad campaigns are more of their strong suit and should capitalize on doing better using social media to outlet these campaigns.
