Does sweaty feet cause excessive sweating?

Plantar hyperhidrosis refers to sweating that is greater than the feet need for cooling. It may occur on its own or alongside sweating of the palms, underarms, face, or other areas. Damp socks and shoes can soften the skin, increase friction, and encourage odour or irritation. Persistent moisture between the toes can also make fungal infection easier to develop. A clinician can distinguish localized sweating from sweating linked to medicines, illness, hormonal changes, or another underlying issue.

Wash and dry the feet carefully, including between the toes. Change socks when damp, rotate shoes so they can dry fully, and select breathable footwear where possible. Avoid applying thick moisturiser between the toes unless a clinician recommends it. A pharmacist or doctor may suggest a suitable antiperspirant or prescription treatment; use products exactly as directed because broken or irritated skin can sting.

Book a medical review if sweating begins suddenly, affects sleep, occurs with dizziness or unexplained weight change, or is accompanied by chest discomfort or breathlessness. Seek care for cracked skin, spreading redness, swelling, pain, discharge, or persistent itching. Assessment is also worthwhile when foot sweating is disrupting work, exercise, social situations, or shoe choice.

Ask whether the sweating is limited to the feet, whether medicines or another condition could contribute, which foot-care products are safe for your skin, and when treatment should be reviewed.
