HW Frost PRO S7S Mid High Safety Boot

HW Frost PRO S7S Mid-High Winter Safety Boot – Waterproof, Grip Sole and SpinOn Roller

HW Frost PRO is a waterproof, lightweight and flexible mid-high winter safety boot for professional use. Its approximately 17 cm shaft extends above the ankle, providing protection against cold, snow and moisture. The boot combines a waterproof HW-TEX membrane, 3M Thinsulate™ 200 g/m² insulation, SpinOn Roller quick-fit fastening and a grippy PU/rubber outsole.

Frost PRO offers good value for money for everyday professional use. Based on practical user experience, the boot is lightweight, flexible and sufficiently comfortable for regular work. However, its fit and ergonomics are not quite at the level of premium safety footwear brands. It is a practical choice when waterproof protection, thermal insulation, flexibility and affordability are the main priorities.

Waterproof HW-TEX Membrane

The HW-TEX membrane helps keep feet dry in rain, snow and wet working environments. It prevents external water from entering the boot while allowing moisture vapour to escape.

The S7S classification includes the WR requirement for whole-footwear water resistance, making Frost PRO suitable for wet outdoor work.

3M Thinsulate™ and CI Cold Insulation

3M Thinsulate™ 200 g/m² insulation helps retain warmth in cold working conditions. The insulated lining is suitable for outdoor work during autumn and winter.

CI cold insulation is a tested property under the EN ISO 20345 safety footwear standard. It indicates cold insulation of the sole construction and complements the thermal protection provided by the Thinsulate lining. The CI marking does not specify a particular minimum operating temperature.

SpinOn Roller Quick-Fit Fastening

The SpinOn Roller fastening system allows convenient tightening and release using a rotary dial without traditional shoelace tying.

Important fitting information: Manual pre-tightening of the laces may be required, particularly around the ankle. The Roller mechanism does not effectively pull the laces over longer distances, especially beyond approximately two lace-loop intervals. Once the laces are positioned and pre-tightened, use the SpinOn dial for final adjustment.

The SpinOn fastening system comes with a 3-year warranty as stated by the supplier.

Mid-High Shaft, Flexibility and Comfort

Frost PRO features a mid-high ankle construction with an approximately 17 cm shaft. It provides additional coverage and support around the ankle compared with low-cut safety footwear.

Based on user experience, the boot is lightweight and flexible. The wide fit provides room for the foot, while the Memory Foam insole improves everyday comfort. However, the overall fit and ergonomics are not quite comparable to more expensive premium safety footwear.

Grippy Outsole and Durability

The PU/rubber outsole provides traction on various working surfaces. The SR classification confirms tested slip resistance according to the relevant safety footwear standard. The HRO marking indicates resistance to brief contact with hot surfaces.

The outsole is not studded, and SR-rated slip resistance does not guarantee traction on ice. Actual grip depends on the surface and weather conditions.

The 1.6–1.8 mm full-grain leather upper and reinforced rubber toe guard improve resistance to everyday abrasion.

Applications

Construction sites, industrial environments, transport, logistics, warehousing, road and infrastructure work, forestry, agriculture, installation and maintenance work in cold and wet conditions.
