My favorite soft hands trainer is free and readily available for those of you who have access to the old rubbery-coated foam type football hip pads. I'm talking about the old school hip pads w/ the two canvas loops the belt slides through, not the more modern ones with the slits the belt weaves through.
Take the pad, put your pinkie through one loop, your thumb through the other, and trim offthe lower end (the end towards the knee).
It has a concave shape that fits the palm better than flat soft-hands trainers.
Sometimes I even wait until the football coach is ready to throw them out before I take them!
