Understanding Dry Soles & Cracked Heels (Anhidrotic Plantar Skin)
What Is Anhidrotic Plantar Skin?
“Anhidrotic” means a lack of sweating. On the feet, this can lead to skin that is very dry, tight, or flaky, especially on the soles. Sweating is important for keeping the skin soft and hydrated. When your feet don’t sweat properly—either due to nerve problems, medical conditions, or genetics—the skin can become dry and more prone to cracking.
Why Does It Affect the Heels?
The heels bear a lot of pressure and movement. When the skin is dry and lacks elasticity (due to anhidrosis), it can’t stretch well. This leads to:
- Cracked heels (heel fissures)
- Thickened skin (callus build-up)
- Pain or bleeding in more severe cases
Cracked heels may also occur more frequently in people with diabetes, eczema, or nerve damage.
Common Causes:
- Diabetes or nerve damage
- Certain medications
- Eczema or psoriasis
- Dehydration
- Standing or walking barefoot often
How to Manage Dry Soles & Cracked Heels
Daily Foot Care Tips
- Moisturize daily with a thick, urea-based or lanolin-based cream
- Avoid harsh soaps that dry out the skin
- Use pumice stone or foot file gently on thickened areas
- Wear cushioned, closed-back shoes to support the heel and reduce friction
Avoid:
- Walking barefoot on hard floors
- Over-exfoliating (can make cracks worse)
- Peeling or cutting thick skin at home
When to See a Chiropodist
- If cracks are deep, painful, or bleeding
- If you have diabetes or circulation issues
- If home treatments are not helping
