The origin of UGG in Australia lies in the wide-open beaches of Byron Bay $-$ a surfers' paradise. Surfers looked for ways to keep their feet dry and warm $–$ and handmade sheepskin boots offered natural warmth and comfort. The foundation was laid for a marketing phenomenon as the global brand now has sales of over US $\$1$ billion. The UGG boot is now globally well known; the promotion focuses on celebrity endorsements and prices are high to reflect the image of the brand. UGG offers online, premium outlets and, increasingly, its own stores as places for customers to purchase just UGG products. These products include more than just boots as there are now UGG men's footwear products and even a range of bridal shoes called 'I Do'! The shift towards increasing its retail operation means that UGG has put more emphasis on the extended marketing mix such as physical evidence. In its shops it has tried to match the fun-loving, free-wheeling image of its brand and its customers. Stores are in high-street locations with a welcoming exterior. Inside, the layout is spacious, light and colourful with quality fittings and furniture. There is ample seating to allow customers and their partners to relax as they try UGG products on for size.

In line with its retail expansion, UGG has upgraded its IT platform to improve the ordering and delivery process. The new software will gather sales, stock and orders in a single system, collecting data from the point of sale. From a customer-service perspective this means that orders can be filled more quickly and a closer relationship established.

Evaluate the importance of the people element of the extended marketing mix to the success of UGG’s retail outlets.
