The Hubby Foot Pump Inflations are rubber tubes that are positioned on the footplate so that they can be easily pumped by the paddlers foot. The pumping action creates pressure in the system causing water to be picked up and expelled from the pump system. 
 
The inflations are manufactured from long lasting rubber and available for K1 (smaller inflation size) and K2 (larger inflation size).
 
Please ask us if you are unsure what would be best suited to your needs.
