Safety shoes Forza BOA Resolute, black/yellow, S1P ESD SRC 4

dynamicHCcontrol technology- Ergonomic rigid internal support. It accommodates the heel, adjusts the way your foot rests on the ground and controls the sideways movement of the ankle. Holds the footwear tightly on the foot and prevents the annoying slipping off feeling.

• D3O® insert is located inside the sole, in the heel area. It helps reduce impacts throughout the day, protects the heels and saves the joints from stress.
• D3O® is SOFT and FLEXIBLE ensuring comfort and long-lasting performance whatever the use. It absorbs and dissipates energy, even when heavily stressed, offering more advanced impact protection than protection provided by other "standard foams".

• No traditional laces.
  A thin steel wire with a nylon coating can be adjusted easily and precisely down to the millimeter.

• How does the BOA system work?
  To tighten, push the dial down and turn it until the shoe fits snugly and comfortably. To take the shoe off, pull the dial up — the wire releases instantly.
