These super light running shoes are actually made from sugar

If you're always thinking about your carbon footprint with every step, then ASICS' new trainers could be the shoes to invest in. The GEL-LYTE III CM 1.95 shoes, which are due to drop early next year, are comprised of recycled and solution-dyed polyester on the upper material of the trainer and the sock liner mesh. 

The average running shoe emits around 13kg of carbon dioxide due to the materials used and how they are disposed of, normally in landfills. ASICS new trainers emit just 1.95kg per pair, so they are a real contender for the best eco-friendly running shoes.
