Diabetic foot care advice is usually delivered as a long list at an appointment, and most of it evaporates by the time you get to the car. Here is the short version of a daily routine that people actually stick to, and an honest note about where socks come into it.
Daily foot care
The two-minute daily check
Look at your feet once a day, at the same time, ideally when you take your socks off in the evening. Check the tops, the soles, the heels, and between every toe. Use a mirror or your phone camera for the parts you cannot see.
You are looking for redness, blisters, cuts, cracks, colour changes, swelling, warmth, or any new sore spot. If you have nerve damage or reduced sensation, your eyes are doing the job your nerves used to. A cut or blister that has not started healing within a day or two is a call to your doctor, not a wait-and-see, because foot ulcers and serious infection can develop faster when you have diabetes.
Keep skin in good condition
Wash your feet daily in warm water, never hot, and dry properly, especially between the toes. Moisturise the tops and soles but not between the toes, because trapped moisture there is where problems start. This helps keep skin clean and dry and lowers the chance of cracks that can become entry points for infection.
Trim nails straight across. If you cannot see or reach your feet comfortably, or your nails are thick, have a podiatrist do it rather than improvising. Straight-across trimming also helps lower the risk of ingrown toenails.

Never barefoot
Not in the house, not at the pool, not for a quick trip to the bin. Reduced sensation and poor blood flow mean you will not feel the piece of glass, the sharp edge, or the hot pavement until damage is done. Grip-soled socks are useful here because they let you cover your feet indoors without the fall risk of smooth socks on tile.
The sock part
Socks matter more with diabetes than most people realise. You want them changed daily, clean and dry, non-binding at the ankle, without a thick toe seam, and ideally structured so your toes are not pressed together sweating all day.
That last point is where NeuroSox five-toe socks are genuinely useful. Individual toe pockets keep skin from rubbing against skin and let moisture escape from between your toes, which is exactly the area you are told to check and keep dry. The compression through the arch is gentle rather than the medical-grade kind, so if your doctor has prescribed a specific compression level, follow that and ask where daily-wear socks fit alongside it.
Shoes, briefly
Check inside your shoes with your hand before putting them on, every time. A small stone or a folded insole can cause real damage to a foot that cannot feel it. Buy shoes late in the day when your feet are at their largest, and never buy anything that needs breaking in.
The point of all this
None of these steps are difficult. They are just easy to skip, and the consequences of skipping them show up slowly. Two minutes a day, clean dry socks, and never barefoot covers most of it.
