Diabetic foot care guide: daily habits & temperature checks

People with diabetes can lose protective sensation in their feet, which means small injuries, friction or inflammation can go unnoticed. Daily foot checks and temperature monitoring help spot problems early.

Why temperature matters

Inflammation raises local skin temperature before redness, swelling or a break in the skin appears. Research on diabetic foot ulcer prevention has shown that a difference of around 2.2 °C between the same spot on each foot can signal an early warning. PodiaScan calls this a contralateral hotspot.

Daily foot inspection checklist

  • Check the tops, soles, heels and between the toes for cuts, blisters or redness.
  • Look for hard skin, corns or calluses that may create pressure points.
  • Feel for warmth using the back of your hand or a handheld thermometer.
  • Never walk barefoot, especially on hot pavements or cold tiles.
  • Moisturise dry skin but avoid applying cream between the toes.

Footwear and activity tips

Choose shoes with a wide toe box, cushioned soles and no internal seams. Socks should be soft, breathable and seam-free. Rotate shoes every day so pressure points vary. If you notice rubbing or a new area of warmth, change footwear and monitor for 24 hours.

When to call a clinic

Contact your foot clinic or GP the same day if you notice a temperature difference between feet, a new blister, redness that does not fade, or any break in the skin. Seek emergency care for open wounds, bleeding or signs of infection such as fever or spreading redness.
