What a simple solution to a the problem of having lots of crochet hooks and arthritic hands.  You don't need to buy another set of ergonomic hooks, as these handles work very well. I have a set of Susan Bates hooks and these cushions transformed them from unusable and painful to comfortable, and come in sizes to accommodate your most commonly used hooks.  Have not found them for 6mm/I-10 size or larger, but the larger hooks are easier to handle than the 2.5, 3.0 etc., anyway. If your hands are as bad as mine, you may need help from someone to put them on your hooks, but once there you are set to go. I have also used them on other brands of hooks, so do feel limited Susan Bates hooks only.  The have worked universally for me.
