Lock Laces fit perfectly on I-Runner shoes, but also any other athletic shoe brand. The firm-but-flexible elastic laces stretch, so you can easily slide your shoes on without damaging the heel of the shoe. The patented double-eyelet lock device makes it easy to make adjustments and holds your laces in place better than any other system on the market.
Patented double eyelet lock securely grips laces to keep them from slipping.
Dial-up the tension to add compression or loosen to relieve your foot and improve circulation.
