To fix heel slip, use effective lacing techniques. Begin with a standard crisscross lacing pattern for a strong base. Create loops by threading the laces through the top eyelets, forming a loop near the ankle. Cross the laces into the opposite loops to anchor the heel securely. Make certain the laces are snug to prevent circulation issues. Use a double knot, like a reef knot, to finalize for a secure hold. Keep going to learn more strategies for best fit.
