Extreme cold can do damage to the soft tissue of the feet. Long periods of extreme cold can freeze and actually kill soft tissues in the foot. Because the blood vessels are most small in the foot the blood, arteries, veins, and capillaries can actually freeze too.
If frozen for long periods of time, the soft tissues can actually die.
Frostbite and chillblaines can be the result.
Prevention is multiple pairs of thick wool socks, and waterproof shoes.
When coming inside after long periods of extreme cold, its is important to warm the foot again, but SLOWLY. Soak them in warm, not hot water. Keep them at inside room temperature- NOT at extreme hot.
If the feet stay painful, red, blue, black or open sores it is important to see a foot specialist ASAP.
PREVENTION is always best.
