| Class | Proteccion | Recommended Workplace |
|---|---|---|
| S1 | Toe protection + antistatic + heel energy absorption | Warehouse, indoor factory |
| S2 | S1 + water-resistant upper | Light wet environments |
| S3 | S2 + puncture resistance + outsole grip | Construction, outdoor work |
| S7 | S3 + waterproof protection |
Mining, heavy industry, wet environments |
