What to check before you buy

NIDDK, the federal research institute for diabetes and kidney disease within the National Institutes of Health, gives plain rules for buying shoes.
Check toe room first: NIDDK says shoes need enough room for your toes. It also advises buying shoes late in the day, when your feet are largest.
Orthofeet describes its extra-depth line on its own site. The points below apply to the line, not to one model:
- Toe area and lining: extra room for toe movement, in a soft, smooth lining padded with extra foam.
- Insoles: orthotic insoles come with every pair.
- Spacers: two sets of removable spacers (2 mm and 3 mm) adjust the space inside the shoe.
- Straps: slip-on shoes carry a strap on both sides.
A smooth lining matters because numb feet may not feel a pebble or a rough spot. NIDDK tells people with diabetes to check inside each shoe first. The lining should be smooth and free of pebbles.
Run a hand around the inside of any pair on arrival. The Performance-X lists a toggle closure, and the three Orthofeet titles name hook-and-loop.
What Medicare covers, in one paragraph
Medicare, the federal health insurance program, mainly for people 65 and over, pays toward therapeutic shoes under Part B. It does so only if you have diabetes and severe diabetes-related foot disease.
Neuropathy from another cause is not the condition its page names.
The doctor treating your diabetes must certify the need, and a podiatrist or other qualified doctor must order the shoes. Your doctors and suppliers must be enrolled in Medicare.
Each year Medicare allows one pair of extra-depth shoes, or one pair of custom shoes or inserts, plus 2 or 3 more pairs of inserts.
You pay 20% of the Medicare-approved amount after the Part B deductible, if your supplier accepts assignment.
When to see a podiatrist instead
A podiatrist is a foot doctor.
NIDDK says to call your provider right away about a cut, blister or bruise not healing after a few days. The same goes for skin that turns red, warm or painful.
NIDDK also says you can ask your provider to refer you to a podiatrist if needed. Do that before buying if you have a foot sore or doubt you can feel your feet.
If your feet are numb, ask your doctor to check them before you order a pair.
Matching the pair to the foot
| Your walk | Take a look |
|---|---|
| Men, double depth, three widths | Dr. Comfort Performance-X |
| Women, three widths and gel insoles | Dr. Comfort Marla |
| Women, leather and mesh, straps | Orthofeet 851 |
| Women, stretch upper, straps | Orthofeet 827 |
| Men, leather, straps | Orthofeet 510 |
NIDDK advises checking your feet every day. The foot check in walking with neuropathy covers a hand inside each shoe and a look at the sole of each foot.
For a woman who needs width choices, buy the Marla. For a man who needs room for braces, AFOs or severe swelling, buy the double-depth Performance-X.
Choose an Orthofeet 851, 827 or 510 when you prefer a strap closure and the listed upper, and check the width options Amazon offers before you order.
