Product Summary
If you suffer with daily foot fatigue at work, try the 'Nitrate' safety boot and feel like you're walking on air all day. This boot has been created with nothing but all-day foot comfort in mind. The results are so great, that we've patented the comfort features you will find in this boot - our patent number 0001402436.
The underfoot comfort is created using 7 different parts:
1. Secosol Certified, Cushioned Orthopaedic Insole (Patent DGUV1112-191)
2. Activated Carbon Lower Insole - creates greater breathability
3. 100% recycled Lightweight underpadding
4. Shock-Absorbing air cushions in the mid-sole
5. Anti-perforation, flexible composite plate (prevents puncture from sharp items)
6. Expanded PU Rubber Springs
7. Anti-static, anti-slip & heat resistant Outsole
Together these features ensure you are comfortable & still enjoy ultimate S3 safety protection at work.
