So you love a particular pair of shoes and the different colors it comes in, but have only enough money to bring home a single pair. What are you to do? Keep your fingers crossed and hope that the Asics Gel Lyte III technology will be exported onto other brands, as this pair of running shoes change color the moment they're exposed to strong sunlight, changing from white to purple. Definitely an interesting novelty, not to mention Asics shoes being rather comfortable to wear no matter the condition. Mark August 23 on your calendar as that's when the Asics Gel Lyte III will be available at retail stores.
