Common Clog Problems and How to Solve Them

Even quality clogs can develop problems over time, and sometimes issues appear right from the start due to fit problems or inappropriate use. Before giving up on your clogs—or worse, suffering through discomfort—try these solutions to the most common clog complaints. Most problems have straightforward fixes that can restore your clogs to comfortable, functional footwear.

This troubleshooting guide addresses the issues I hear about most frequently from clog wearers. Whether you're experiencing blisters, odour, wear problems, or comfort issues, you'll likely find helpful solutions here.

Problem: Blisters and Rubbing

Blisters are friction injuries, typically occurring when your foot slides against the clog material repeatedly. This is one of the most common complaints, especially with new clogs.

Causes

• Improper sizing: Too large causes sliding; too small causes pressure points
• Break-in period: New clogs haven't softened or moulded yet
• Missing heel strap: Foot slides forward and back excessively
• Sockless wear: More friction without sock buffer
• Moisture: Sweaty feet increase friction

Solutions

For new clogs: Break them in gradually—wear for short periods, increasing over time. Use moleskin or blister bandages on problem areas during the break-in period.

For fit issues: If clogs are too large, try wearing thicker socks or adding a heel grip pad. If consistently getting blisters regardless of sock use, the clogs may simply be the wrong size or shape for your feet.

For ongoing friction: Apply a thin layer of petroleum jelly or anti-chafe balm to friction points. Consider thin moisture-wicking socks that reduce direct contact while managing sweat.

Problem: Persistent Odour

Smelly clogs are embarrassing and unpleasant. The odour comes from bacteria thriving in the warm, moist environment created by sweaty feet.

Causes

• Wearing clogs without socks allows sweat to accumulate on footbed
• Not allowing clogs to fully dry between wearings
• Porous materials absorbing sweat over time
• Inadequate cleaning routine
• Foot conditions that cause excessive sweating

Solutions

For mild odour: Create a paste with baking soda and water, apply to footbed, leave for 15-30 minutes, then scrub and rinse thoroughly. The baking soda neutralises odour-causing acids.

For moderate odour: Mix equal parts white vinegar and water in a spray bottle. Spray the footbed generously, let sit for 10 minutes, then wipe clean and air dry completely. Vinegar kills bacteria while the smell dissipates as it dries.

For severe odour: Soak EVA or rubber clogs in a solution of warm water with a few tablespoons of baking soda for an hour. For cork footbeds (which shouldn't be soaked), try activated charcoal inserts or commercial odour eliminators.

Prevention: Rotate between pairs to allow complete drying. Sprinkle baking soda on footbeds overnight periodically. Consider wearing thin socks to absorb sweat rather than letting it contact the footbed directly.

Problem: Foot Pain and Fatigue

Clogs should be comfortable. If your feet hurt, something needs to change.

Arch Pain

Cause: Inadequate arch support or arch support that doesn't match your foot type.

Solutions: If clogs are otherwise good quality, try adding an aftermarket insole with appropriate arch support (requires sufficient depth in the clog). For flat-footbed clogs, consider upgrading to a brand with built-in arch support. Some people need higher or lower arch support than "standard"—experimentation may be needed.

Heel Pain

Cause: Inadequate cushioning, heel cup issues, or underlying conditions like plantar fasciitis.

Solutions: Ensure the heel cup centres your heel properly. Add gel heel pads for extra cushioning. If pain persists, consult a podiatrist—clogs may not be suitable for your specific condition.

Forefoot Pain

Cause: Toe box too narrow, clog too short, or excessive pressure on the ball of the foot.

Solutions: Verify sizing—toes should not touch the front. Look for wider toe box options. Some designs cause more forefoot pressure than others; try different models.

General Fatigue

Cause: Compressed or degraded cushioning, clogs worn beyond useful life, or clogs inadequate for the duration/intensity of wear.

Solutions: Replace worn clogs—if the footbed doesn't spring back when pressed, cushioning is gone. For long workdays, invest in premium clogs with superior support and cushioning. Not all clogs are designed for all-day wear.

Problem: Heel Slippage

The heel popping out or sliding excessively is both annoying and potentially dangerous.

Causes

• Clogs too large overall
• Heel strap worn or not used properly
• Heel cup too shallow for your heel shape
• Material has stretched with wear

Solutions

Size issues: If significantly too large, you may need smaller clogs. Minor looseness can be addressed with thicker socks or heel grip pads that stick to the inside back of the clog.

Strap issues: Always wear the strap behind your heel for activities beyond lounging. If the strap has stretched, some designs allow replacement. A too-loose strap provides no security.

Heel cup issues: Some foot shapes simply don't work with certain heel cup designs. If you've tried adjustments without success, look for clogs with deeper heel cups or enclosed-back designs.

Problem: Material Degradation

All materials degrade eventually, but premature deterioration is frustrating.

EVA Cracking

Cause: UV exposure, heat damage, or cheap materials lacking stabilisers.

Solutions: Unfortunately, cracked EVA cannot be repaired. Store clogs away from direct sunlight and heat. Choose quality brands with UV stabilisation. Cracks indicate end-of-life—replace to avoid sudden failure during wear.

Sole Separation

Cause: Adhesive failure, often accelerated by water exposure, heat, or simply wear.

Solutions: Minor separation at edges can sometimes be re-glued with appropriate shoe cement (not regular superglue). Clean both surfaces, apply adhesive, and clamp or weight overnight. Major separation usually means replacement time.

Cork Footbed Issues

Cause: Excessive moisture, lack of sealing maintenance, or age.

Solutions: Dry cork footbeds thoroughly after any moisture exposure. Apply cork sealant periodically (especially in dry climates). Some brands offer footbed replacement—check if available for your clogs.

Leather Deterioration

Cause: Lack of conditioning, excessive moisture, or age.

Solutions: Regular conditioning keeps leather supple. Dry wet leather slowly at room temperature (never with heat). Deep cracks indicate leather has passed maintainable condition.

Problem: Loss of Traction

Slipping on surfaces where you previously had grip indicates worn tread—a safety concern.

Causes

• Normal tread wear from use
• Rubber compound hardening with age
• Contamination filling tread grooves

Solutions

For contamination: Clean tread thoroughly, removing any debris from grooves. Sometimes accumulated grime significantly reduces grip.

For wear: Visually inspect tread depth. If significantly worn smooth, especially in high-wear areas, replacement is needed for safety. No DIY solution restores worn tread.

For hardened rubber: Rubber outsoles harden with age, reducing grip even if tread depth looks adequate. If clogs are old and feel less grippy despite visible tread, the compound has aged out.

Problem: Hot Feet

Clogs can become uncomfortably warm, especially fully enclosed waterproof designs in summer.

Solutions

Socks matter: Thin moisture-wicking socks can actually cool feet by moving sweat away from skin, despite adding a layer. Cotton socks retain moisture and increase heat sensation.

Ventilation options: If waterproofing isn't essential for your use, consider clogs with ventilation holes for warm weather. Some designs offer removable vent plugs for versatility.

Rotation: Having a spare pair allows removing clogs during breaks, letting feet cool and clogs dry.

Climate-appropriate choices: Accept that fully enclosed waterproof clogs may not suit extreme heat. Have ventilated options for hot days when waterproofing isn't needed.

When to Replace Rather Than Repair

Some problems can't be fixed—recognize when it's time for new clogs:

• Structural cracks in the sole or upper
• Permanently compressed cushioning that doesn't rebound
• Smooth tread in critical areas
• Persistent odour that doesn't respond to cleaning
• Material separation that recurs after repair
• Fit changes that cause recurring problems
