Smelly climbing shoes can kill your vibe before you chalk up. If your shoes emit more funk than grip, you’re not alone. The right routine makes odor fade without sacrificing performance.
Odor develops from sweat, bacteria, and damp environments. A quick routine can reset that scent without harsh chemicals. Keep reading for practical steps you can use after every session.
First, air and dry your shoes after training to reduce moisture. Wipe the interiors with a damp cloth and a mild cleaner if needed – never soak. Let them dry away from direct heat to protect materials.
Second, use odor absorbers like baking soda or specialty sprays, but don’t overdo it. Leave them in overnight for best results, then shake out before your next climb. Rotate between pairs to give each set time to recover.
Finally, pair these habits with breathable socks and proper shoe storage. Regular washing of laces and insoles can help, too. With consistency, you’ll notice fresh feet and a more confident session.
Causes and Material Interactions That Fuel Odor
What Makes Climbing Shoes Stink?
Climbing shoes are dynamic micro-ecosystems: feet sweat heavily during climbs, and the toe box often stays damp long after a session ends. This warm, moist environment becomes the perfect breeding ground for bacteria and fungi that metabolize sweat into volatile compounds your nose recognizes as odor.
As you train, the same pair of shoes undergoes repeated exposure, and without adequate airing, moisture accumulates and microbes multiply. The smell isn’t just sweat; it’s a byproduct of microbial life interacting with moisture, heat, and the porous materials that make up most climbing footwear.
How Materials Affect Odor Absorption and Release
Leather is porous and tends to absorb moisture, storing odors longer than slick synthetic uppers. Synthetic fabrics can wick moisture, but their microfibers often trap odor-causing compounds inside the weave, making the stink harder to remove once it takes hold.
Insoles and foams complicate odor control because they harbor bacteria and compress over time, creating micro-niches where odors linger. Knowing how materials behave helps you tailor cleaning: treat leather with care, prioritize breathable synthetics, and choose insoles designed to dry quickly and resist odor buildup.
Immediate Post-Use Actions to Neutralize Odor
Quick Deodorizing Steps Right After a Climb
Immediately after finishing a session, remove the shoes and take out the insoles to minimize moisture retention. A quick spray with a general footwear deodorizer or a light dusting of baking soda inside the shoe can begin neutralizing odors before they set in.

Shaking out debris and wiping down the interior with a damp cloth helps remove sweat and grime that feed bacteria. If you’re using baking soda, consider leaving a small amount inside the shoe overnight and then brushing it out before your next session.
Drying and Airing Strategies to Prevent Odor Escalation
Airflow is your primary defense against odor. Stand shoes on their sides with openings open, or place them in front of a fan to promote thorough drying rather than relying on direct heat. A dry, well-ventilated space reduces bacterial growth dramatically.
Use moisture-absorbing aids to accelerate drying: newspaper, silica gel packs, or vented shoe bags help wick moisture away from the lining. Avoid placing shoes near heaters or radiators, which can denature materials and trap odors rather than eliminate them.
Cleaning Insoles and Interior Properly
Removing Insoles and Washing Them
Take out the insoles first, inspecting them for wear or delamination that would reduce their odor-control effectiveness. Hand wash insoles in warm water with a mild detergent, rinse thoroughly, and air dry completely away from direct sunlight.
If insoles retain odor after drying, you can refresh them with a diluted vinegar solution (one part vinegar to four parts water) or a baking soda paste. Rinse or brush away residues and allow full air drying before placing them back inside the shoes.
Cleaning the Shoe Interior Without Damage
Wipe the interior with a microfiber cloth dampened with a mild soap solution to remove sweat and residue from the lining. For tougher smells, a gently diluted solution of white vinegar can be used on the cloth, but avoid soaking, especially in leather interiors that may warp or stiffen.
After cleaning, let the shoes dry in a well-ventilated area, away from heat sources. If you use sanitizer, apply lightly and sparingly to limit any potential impact on adhesives or materials, and always test on a small inconspicuous spot first.
Home Remedies and Odor Absorbers
Baking Soda, Activated Charcoal, and Silica Gels
Baking soda is a cheap, effective deodorizer: sprinkle a small amount into each shoe and leave it overnight to absorb moisture and odor. In the morning, shake out the powder and store the shoes with a small sachet of baking soda if you won’t climb again for a while.
Activated charcoal or other odor-absorbing sachets pull molecules from the air inside the shoe and help maintain a fresher environment between sessions. Silica gel packs placed inside shoes during storage can also reduce residual humidity and slow odor formation. (See Also: Top Guide: How to Clean Vegan Leather Shoes for Beginners)
Vinegar, Lemon, and Essential Oils: Uses and Cautions
A diluted vinegar spray (one part vinegar to four parts water) can kill some odor-causing bacteria and fungi when applied to the interior, but never saturate leather or foam materials. Lemon juice offers a natural scent but can be acidic enough to affect certain fabrics; test a small area first.
Essential oils such as tea tree, eucalyptus, or peppermint can provide fragrance and antimicrobial benefits when diluted properly. Use only a few drops per spray and ensure they don’t irritate the skin or damage materials, testing on a small area before widespread use.
Product Options and Gear-Specific Care
Antimicrobial Sprays and Inserts
Antimicrobial sprays formulated for footwear can be used after cleaning to reduce lingering bacteria and fungi between sessions. Follow the product instructions for frequency and ensure the spray dries fully before wearing the shoes again.
Odor-control inserts and in-shoe insoles, especially those with activated carbon or antimicrobial properties, can substantially cut odor buildup. Choose inserts that fit snugly and dry quickly to prevent moisture retention that fuels bacteria growth.
Leather vs Synthetic: Care Differences and Best Practices
Leather shoes require gentler handling: avoid soaking and use a leather-safe cleaner or conditioner after cleaning to maintain suppleness. Dry thoroughly and avoid heat sources that can cause cracking, which would trap dirt and odors more easily.
Synthetic shoes tolerate more aggressive cleaning and air-drying, but still benefit from a breathable drying environment and fan-assisted drying. Avoid harsh solvents that could degrade adhesives; potassium-based cleaners and mild detergents are typically effective without harming the structure.
Prevention Strategies for Long-Term Odor Control
Foot Hygiene, Socks, Moisture Management
Daily foot hygiene matters: wash feet thoroughly, dry completely, and monitor skin for signs of irritation or fungal infection. Wearing moisture-wicking socks reduces the amount of sweat that penetrates into the shoe.
Change socks between sessions when possible, especially after intense climbs or in hot climates. Consider rotating different pairs of socks to reduce continual exposure to the same bacteria and moisture source.
Storage, Rotation, Airflow, and Drying Aids
Store shoes in a ventilated area rather than in a closed gym bag, which can trap moisture and foster odor. Rotating between two pairs allows each pair to fully dry before reuse, reducing odor carryover. (See Also: Top Tips: How to Stop Tennis Shoes From Squeaking)
Use drying aids like silica gel packs or dedicated shoe deodorizers in your gear bag and at home. Ensure the environment remains dry and well-ventilated to prevent mold growth and odor recurrence over time.
Troubleshooting and Advanced Options
Persistent Smell After Cleaning: Deeper Cleaning Steps
If odor persists after standard cleaning cycles, repeat the cleaning process, focusing on the insole and interior surfaces where bacteria may linger. Use a enzymatic cleaner designed for footwear to break down organic residues more effectively than soap alone.
Extend drying times between sessions and ensure complete moisture removal before using the shoes again. Consider a light surface wipe with isopropyl alcohol on interior surfaces if safe for your shoe materials, followed by thorough air drying.
Mold Remediation and Professional Cleaning Options
For visible mold or persistent musty odors, treatment becomes more involved. Mild household solutions can help, but mold may require more aggressive sanitation or replacement of affected components like cushions or insoles.
Professional cleaning services specializing in athletic footwear can provide deeper deodorization and material-safe treatments. If odor returns after repeated attempts, evaluating the internal structure and replacing worn components may be the most cost-effective long-term solution.
Conclusion
Effective odor control hinges on understanding why climbing shoes stink and applying targeted care across cleaning, drying, and preventative practices. Consistent, material-aware maintenance—paired with good foot hygiene and smart storage—reduces microbes, moisture, and odors at the source. With a structured routine, you can keep your shoes fresher longer and climbing more comfortably.
