Heavy construction use requires replacement every 6–12 months; light warehouse work can extend to 12–18 months, even if the upper looks intact.

Yes. PU midsoles degrade via hydrolysis after 3–5 years even without wear. Store spare pairs in dry 15–25°C spaces with desiccants to slow material aging.

Only minor fixes like lace and insole replacement are allowed. Any crack on toe caps, peeled midsoles or broken anti-puncture layers void safety certification; such shoes must be discarded immediately.

Composite toes are recommended for electricians—they avoid conducting electric current. For winter sites below -10°C, composite toes stay 5–8°C warmer than steel toes that absorb cold rapidly.

Yes. Both meet identical ASTM and EN ISO 20345 impact standards. Composite caps use carbon fiber and fiberglass, matching steel’s load-bearing capacity without metal weight or temperature conductivity.

Footwear must pass ASTM F2413-24 testing, with clear internal labels showing impact (I), compression (C), puncture resistance (PR) or electrical hazard (EH) ratings. Unmarked uncertified shoes cannot be used on regulated job sites.

Yes. Per 29 CFR 1910.136, employers must provide compliant protective footwear if staff face falling objects, sharp puncture risks, rolling heavy materials or electrical hazards. Non-compliance leads to fines and higher workplace injury compensation costs.
