role in fit and comfort. A shafted boot (e.g., a 6” or 8” tall boot) of- fers more ankle stability than a shorter boot (e.g., an oxford).
Midsole
The midsole should provide ample support and stability is are important for the overall structural integrity of footwear.
Durability
Slip resistance performance may change as footwear undergoes normal wear and tear. Employers should prioritize durable foot- wear that provides the most slip resistance for the longest period of time.
Setting the Standard
Any safety footwear provided can claim slip resistance, precisely because there is no uniform standard or rating for slip resistance. For this reason, Red Wing Shoe Company recommends three sim- ple principles for evaluating slip resistance:
1. Follow the ASTM standard test method. ASTM F2913 pro- vides the most complete approach to evaluating how different foot- wear materials interact with various work surfaces. All slip resistant footwear should be tested to this standard to establish a common basis for comparison.
2. Understand the details. Whether or not a specific shoe or boot will provide adequate, long-term slip resistance requires a deep un- derstanding of what the job actually involves: the surfaces, contam- inants and physical requirements of the role. Look for a provider with experience developing purpose-built safety footwear worn in a variety of industries.
3. Share knowledge. Ensuring slip resistance depends on a strong, open and transparent collaboration between employer and safety footwear provider. The footwear manufacturer should provide detailed information about its products and their perfor- mance, while understanding the work environment they are best suited for.
