If you’re constantly swapping socks or slipping in your sandals, you’re not alone—sweaty feet in summer are a common complaint. But when does it cross the line from a seasonal nuisance to something that needs professional care?

Excessive foot sweating, or plantar hyperhidrosis, can be triggered by summer heat, increased activity, or even stress. In many cases, it’s perfectly normal. The sweat glands in your feet are more concentrated than in other parts of your body, so it’s natural for them to work overtime during hot weather.

But when sweating becomes excessive—soaking through shoes, creating persistent odor, or leading to skin problems—it’s worth a closer look. Excess moisture can cause painful blisters, fungal infections like athlete’s foot, and even breakdown of the skin. If you already have conditions like diabetes or eczema, this can make you even more vulnerable to complications.

At Gauld Foot and Ankle, we start with a full skin and sweat gland evaluation. Treatment may include clinical-strength antiperspirants, moisture-wicking socks, and in some cases, oral medications or iontophoresis (a therapy that temporarily reduces sweat gland activity). We also review your footwear habits and recommend supportive, breathable shoes to help manage sweat during the hottest months.

If sweat has already led to nail or skin buildup, we can clean and treat it in-office. For long-term cosmetic maintenance, we may recommend a visit to our partner Sona Medical Pedicure Spa—especially if your feet are prone to skin infections or nail thickening due to moisture.

Don’t let sweat slow you down. Book your appointment with Gauld Foot and Ankle and find a solution that keeps your feet cool, dry, and summer-ready.
