The findings are most consistent with contact dermatitis, very likely leather/strap-induced allergic or irritant dermatitis.
Supporting points:
• The redness, scaling, and small open circular blisters are exactly in the areas where the chappal strap touches the skin
• Rest of the foot is relatively spared
• Appearance suggests eczema-like inflammation, not infection
• This pattern is not typical of fungal infection, cellulitis, or vascular disease
Common triggers include:
• Leather tanning chemicals
• Rubber/adhesives in footwear
• Sweat + friction under straps
This condition is treatable and reversible if addressed early.
Next Steps
1. Immediately stop wearing the offending chappal
• Switch to soft fabric footwear or open slippers
2. Topical treatment (short course):
• A mild-to-moderate steroid + soothing agent (e.g., mometasone or hydrocortisone-based cream) once daily for 5–7 days
• If oozing is present, add a non-steroidal barrier or zinc-based cream
3. If itching is significant:
• An oral non-sedating antihistamine at night can help
4. Consult a dermatologist if:
• No improvement in 5–7 days
• Worsening redness, pain, pus, or fever develops
Health Tips
• Keep the area clean and dry, but avoid over-washing
• Do not scratch or peel blisters
• Avoid home remedies like toothpaste, turmeric, or antiseptic spirits
• Once healed, reintroduce footwear cautiously—prefer hypoallergenic, fabric-lined straps
• Moisturize daily after healing to restore skin barrier
This looks like a localized skin reaction, not something serious or permanent. With simple avoidance and short treatment, most patients recover quickly and completely.
