Sievi's safety work shoe, Sievi Spike 3, has reversible heel studs. The Sievi Spike stud mechanism and other safety features such as steel toe and nail penetration protection make these a safe choice for slippery and demanding winter working conditions. The completely renewed and patented Sievi Spike stud mechanism, integrated into the sole structure of the winter safety shoe, provides sure grip in challenging conditions. The new technology allows the studs to be turned in and out without taking off the shoes. The upper material used in the safety ankle boots is, among other things, water and dirt-repellent PU leather, which withstands heavy use and the warm lining keeps the feet warm throughout. The sole is heat resistant up to 120 degrees. The memory foam ankle protectors individually shape to the user's foot and provide support and protection for the ankles. The safety shoes have Sievi Dual Comfort insoles, which have a PORON® shock-absorbing pad in the heel and instep, which further absorbs external shocks and strain.
