Rafael, Hi from CKF. I have fussed with seats for both leg and back comfort and discomfort. For sleepy feet a longer seat forward with support under the thighs, less weight on the two sit bones, and more support around the perimeter of the seat takes the weight off the nerve that goes to your legs. Not your described problem but the most common discomfort. Low back pain after long distance for me was caused by too much back support too high. I lowered the backband below the small of my back (and hip bones) and loosened it up to provide support only when I lean back from my paddling position. An even better solution was eliminating the back band and using a small wedge of minicell foam extending above my 3-inch-deep carved-minicell seat. The wedge is only 4 or 5 inches wide centered above the seat to provide support on the back of the pelvis when leaning back or when pushing on the footbraces while still allowing good hip rotation.
