Abstract
Sporting footwear, such as a mountain boot or hockey boot or training boot, formed of injected plastics, has integral lacing projections formed on overlapping front closure flaps forming parts of the boot upper. The integral projections provide for easy zigzag lacing of the boot with security and economy of manufacturing. Protrusions integrally formed on the boot upper between adjacent pairs of lacing projections and spaced from the projections bear frictionally on the lace engaged with the integral projections. Tightening of the lace is enhanced while the lace is under tension and loosening of the lace is hindered when the lace is slackened and has its cross section increased.
