With the Super Foam sole that resists hydrocarbons and HRO temperatures, the SIR399 guarantees you stable footing on any surface!

    Amazing shoe, I've had them for 3 and a half months with very hard use and they're still waterproof. I stepped in water over 5 centimeters deep for quite a while and not a drop got in. Quite light and very soft like a sports shoe, I will definitely buy it again!!!

    Nice shoe, very convenient lacing, but for it to crack in various places within three months with use mainly in a warehouse and very little on a construction site, and with a purchase price of €150, I would not recommend it
