The Delta One K-Reinforced foot pocket first of all is made of 55 Shore hardness natural rubber, a material that maintains mechanical characteristics (hardness and elasticity) along time, without deforming or hardening. Moreover, natural rubber, diversely to thermoplastic, does not present great variations of its hardness with temperature. It is in fact true that many low quality foot pockets become very hard in Winter with very low water temperatures (10-15°C), while they become too soft in Summer, with sea water temperature over 25°C. The longerons are instead of 80 Shore rubber, to give more consistency to the lateral connection to the blade.
The top of the line foot pocket by Salvimar has as extremely innovative and intelligent element a Kevlar band inside the rubber, at the height of the instep, exactly where most of the push is transmitted from the foot to the foot pocket to the blade. Since Kevlar does not elongate, in fact, the foot pocket on the instep, even though it remains soft thanks to a not too hard rubber, transmits all the push possible to the blade. From this solution comes the name K-Reinforced.
This foot-pocket is for use in combination with removable blades. It accommodates plastic, fibrerglass and carbon fiber blades. The end result is an exceptional product that is both powerful in the water and very comfortable to use. Sold as a pair.
