Blister

Blisters

A blister is a small pocket of fluid that forms between layers of skin, usually due to friction, pressure, heat, or moisture. They are common on the feet, especially when wearing new, poorly fitting shoes or wearing wet or rubber shoes.

Why Blisters Form

• Friction from new or tight shoes

• Excess moisture or sweating

• Heat or prolonged walking and running

• Repetitive rubbing on a specific area

• Foot shape or gait issues that increase pressure

• Wearing shoes without socks

Common Signs of a Blister

• A raised bubble filled with clear fluid

• Redness or irritation around the area

• Tenderness or a burning sensation

• A “hot spot” feeling before the blister fully forms

When Blisters Need Care

A blister should be assessed or treated when it:

• Becomes painful or interferes with walking

• Shows signs of infection (increasing redness, warmth, pus, or odour)

• Repeatedly forms in the same area

• Occurs due to poorly fitting footwear

• Is large, tense, or located in a high‑pressure area

Safe Management & Natural Support

• Do not break blisters if they are intact and not infected — the skin acts as a natural protective barrier

• Keep the area clean and dry

• Apply a protective dressing or blister plaster to reduce friction

• If the skin has broken, gently clean it with salt water and cover it with a proper sterile dressing

• If a blister bursts on its own, keep the loose skin in place as a natural dressing

• Monitor for signs of infection and seek professional care if symptoms worsen

Prevention & Footwear Assessment

• Assess new shoes for rubbing points before wearing them for long periods

• Identify hot spots early — areas that feel warm or irritated before a blister forms

• Use taping, padding, or blister‑prevention patches to protect vulnerable areas

• Wear moisture‑wicking socks to reduce friction

• Ensure shoes fit properly with enough room in the toe box

• Break in new footwear gradually
