Grisport Constrictor BOA Safety Work Shoes S3
The Grisport Constrictor BOA Safety Work Shoes represent a premium choice for professionals who demand both performance and reliability on site. Part of Grisport's acclaimed Super Trail System collection, these safety shoes combine innovative engineering with practical everyday wearability. The standout BOA rotary closure system delivers quick, precise adjustments without fussing with traditional lacing, whilst the exclusive Vibram TPU sole-developed specifically for Grisport-offers exceptional grip and remarkable durability across demanding work environments. Built to EN ISO 20345 standards, they provide comprehensive protection with an aluminium toe cap and flexible Kevlar midsole that absorbs impact whilst remaining lighter and warmer than traditional steel alternatives. The Cambrelle lining keeps feet dry and comfortable throughout the working day, whilst the modern sole design and reflective strip enhance both safety and visibility on site.
Key Features
- BOA rotary closure system for swift, secure adjustments
- Vibram TPU sole engineered for superior grip and wear resistance

Recommendations from our Unishore Expert
These safety shoes shine when you're working across construction sites, transport operations, or warehouse environments where protection matters. The BOA closure is genuinely convenient if you're moving between different work areas and need to adjust fit quickly. The breathable lining works well for longer shifts, preventing that clammy feeling by the end of the day. The flexible Kevlar midsole is a smart upgrade over traditional materials-you get solid protection against penetration whilst enjoying a more natural walking motion. The sole's grip pattern handles both wet and oily surfaces confidently, which counts for a lot in practical work settings. These shoes offer rigorous safety protection according to strict industrial standards, making them a solid investment for professional use.
