Flex Rating: 7 out of 10
Wrap Liner: The liner is almost like a neoprene material, and when the boot is laced up, it gives a little more support and greater comfort to the rider. Laces are not needed with this liner, as the friction from the overlap adds enough support.
Flex Rating: The flex rating of a boot refers to how stiff the boot is, the higher the relative rating the stiffer the boot. Some boots will list 4 of 5, others may list 8 of 10; two such boots should have similar flex. In general more beginner rider wants a lower flex and more advanced rider a higher flex, but this is not always the case as some beginner riders like more support and some advanced riders like more give.
Removable Liner: This boot comes with a removable liner. Removable liners have the advantage of being easier to dry than non removable liners, and the disadvantage of usually being a little larger than a non removable linered boot of the same size.
Dual Density Rubber Sole: One type or rubber to add stiffness to the sole, a softer rubber to increase grip.
EVA Upper: EVA material for the upper for a soft touch feel mixed with durability.
Integrated Heel Counter: A fancy name for a piece of plastic in the heel that gives extra support.
Soft Touch Laces: Softer material used so your hands and fingers don't get torn up while tightening the laces.
Steel Hardware: The eyelets and other critical parts of the lacing system are made of steel for increased wear.
