The Khaki Green SOF Version has been co-developed by Operators Skincare and Armaskin for the Royal Danish Special Operations Forces.

They are a must-have for all soldiers training for or attending selection course for Special Forces, or participating in the grueling Nijmegen Four Days March.

The secret to the SOF ArmaSkin break-through in Anti-Blister performance is the Si Fusion fabric that provides a slightly sticky Silicon layer next to the skin.

This fabric was designed and created by ArmaSkin after years of research and testing. SOF ArmaSkin prevent the conditions that contribute to blisters; friction on the skin, skin weakening moisture, destructive heat and shear forces between skin layers. The unique features are:

• The inner surface of the sock has a silicone (Si) polymer friction coating which gently adheres to the skin and prevents any friction that can occur naturally between socks and skin. Any friction generated in the boot/shoe is absorbed by the outer fabric.
• The polymer coating is macro porous and hydrophobic (water hating) therefore shifts moisture away from the skin keeping it drier.
• Better heat dissipation is achieved thanks to the hydrophobic/ hydrophilic moisture management. i.e one side of the fabric is water hating the other side is water loving.
• The Si fusion polymer coating gently adheres to the skin and importantly shares skin shear forces across wider surface areas of skin thus reducing damage. 
• The Silicon fusion polymer is bacteria static so the socks can be worn for prolonged periods of time
• Wash them with your normal clothes but avoid using bleach, fabric softener or sending them to the dry cleaners
• As a guide you can expect minimum 500 km blisters free movement if you follow our care instructions.

The SOF Anti-Blister Sock, Long comes in three sizes: Small, Medium and Large.

If your size falls in two size categories we would recommend going for the larger size unless your foot is very narrow.
