Think wearing leather is inhumane? Then try this on for size: Thailand-based shoe company Rayfish Footwear actually breeds live bespoke stingrays, harvesting them for their leather to make each pair of custom-designed sneakers. Using a process known as “bio-customization,” the company combines patterns and colors from dozens of ray species, resulting in a transgenic “designer stingray” like no other. Thinking about investing in a pair of custom sneaks? Better save your pennies — pair of Rayfish sneakers starts at a whopping $14,800.
