Parkinson’s patients have a tool to solve the problems with tying shoes.

Ulaces are short elastic bands which when used in place of regular laces turn the shoes into “slip ons”. I removed the standard laces from my gym shoes and inserted these Ulaces in their place. Now my gym shoes slip on easily. The Ulaces are just snug enough to prevent the shoes from slipping off. Get more info at https://www.u-lace.com
My gym shoes were always coming untied, so I set out to find a solution. The solution I found was these u-lace things which replace traditional laces altogether. They’re elasticized bands that resemble mini laces. See u-lace.com.
