Insoles with Antistatic Thread Lahti Pro model 40 — replacement shoe insoles, size 40

Lahti Pro replacement insoles size 40 are removable shoe insoles with an integrated antistatic thread, designed to reduce electrostatic buildup while providing basic foot support. These insoles fit footwear that accepts size 40 inserts and are intended for both work and everyday shoes where antistatic properties are required. The construction focuses on compatibility, ease of replacement and reliable static dissipation without altering the shoe's internal fit significantly.

Advantages

These insoles incorporate a conductive thread that helps dissipate electrostatic charge, reducing the risk of static shocks in dry environments or while working with sensitive equipment. The size 40 format provides a standardized fit for compatible shoes and can be easily removed and replaced for cleaning or swapping. Materials are selected to offer basic cushioning and breathability while maintaining low-profile thickness so the original shoe fit is preserved.

Suitable for

• Work shoes in environments where electrostatic discharge (ESD) control is desirable
• Everyday footwear where occasional static shocks occur
• Shoes used around electronic equipment or indoors with low humidity
• Replacement of worn or uncomfortable factory insoles in size 40 shoes

Key specifications

• Size: 40 (replacement insole format compatible with size 40 footwear)
• Feature: integrated antistatic (conductive) thread for static dissipation
• Type: removable, replaceable insole
• Profile: low-profile design to preserve interior shoe fit
• Intended use: suitable for work and everyday shoes requiring antistatic properties

How to use

Remove the existing insole from the shoe if present, check that the shoe interior is clean and dry, then insert the Lahti Pro antistatic insole with the top side facing up. Trim to fit only if necessary and if the insole material allows trimming along the edges. Replace insoles on both shoes to ensure consistent fit and static performance. Periodically remove the insoles to air out and inspect for wear; replace when cushioning or conductive properties degrade.

Usage recommendations

For effective antistatic performance, use the insoles in shoes worn on non-insulating floors or together with appropriate footwear grounding measures when working with sensitive electronics. Keep insoles dry and clean; avoid machine washing unless manufacturer instructions permit. Replace insoles when visible wear or loss of cushioning occurs.
