Non-tying active laces with patented elastic technology that provides adjustable tension between shoe eyelets. Premium laces designed to enhance a broad range of shoes. EASY TO INSTALL & REUSE : Put in Caterpy laces as you would with traditional shoelaces, there is no extra hardware to install. You just lace up once and never need to touch your laces again. The laces can be taken out and reused for multiple pairs of shoes. CONVENIENT SLIP-ONS : Transform your favourite pair of shoes into slip-on shoes. Take your shoes on and off without readjusting laces everyday; and avoid breaking the heel of your shoe from cramming your foot into it. ELASTIC COMFORT : Our elastic laces improve your feet's blood circulation as they naturally swell throughout the day. Knots from traditional laces create choking points and constrict your feet. CUSTOMISED PERFORMANCE : Our patented elastic bump technology secures tension in each row of the shoe. This allows you to create customised tension throughout all eyelets, instead of relying on a single knot or plastic piece. FEEL THE DIFFERENCE : Once you try a pair of Caterpy and feel the difference, you will never want to go back to traditional shoelaces. Caterpy laces are guaranteed to last the life of at least one pair of sneakers.
