Black Kmart bamboo fibre crew socks. I have about 6 pairs (they’re cheap) and have them on high rotation. They’ve done about a year now and are still pretty much as good as new. Excellent support, and they stay up really well too. I too have wide feet, so these have been a lifesaver. No holes as yet. They do have fierce elastic at the tops, so if you have circulation issues these might not be the best choice. I wash them in the regular laundry and air dry if possible and finish them off in the tumble dryer if not.
