Perry Crays of Michigan was walking on a narrow beam about 8 to 10 feet off the ground when the laces from his right boot caught the hook eyelets from his left boot, causing him to trip, fall, and disable himself. He sued the Meldisco Shoes Corp., supplier of the boots, and K-Mart, the retailer, saying the boots should have been designed differently or carried some kind of warning about possible risks to wearers. A jury found for Crays, and the decision was upheld by the Michigan Court of Appeals.
