Fluid Motion EVO boots use a large King Cord Lock + retainer tie wrap for the main lacing system.
The REVO boots use a smaller spring loaded Bottle style lock for the front toe lace on a buckle closure boot.
Specially sized to fit FM's premier marine cord lacing systems. The cord lock closure allows you to tighten and loosen the cord lacing length to adjust the fit of your Fluid Motion boots.
Note: Sold as single units. Please order qty; 2 if you need a pair.
