"Penguins feet are never allowed to get below freezing point, blood flow is finely adjusted so that they are kept just above. When it gets very cold, the feet are covered by the feathers and fat layer of the body so they are not exposed to cooling winds."
"At low temperatures or when in the sea, the blood flow to feet and flippers is very low anyway so reducing heat loss further."

"The muscles that operate feet and flippers are not located in the feet and flippers, but deeper in the warmer regions of the penguins body. The feet and flippers are moved by tendons that pass through them and attach to toes etc. like a sort of remote operation by wire or string. This means that it doesn't matter if the feet and flippers get really cold as they can still be operated normally by regions that are fully functional and at normal body temperature."

"King and emperor penguins are able to tip up their feet, and rest their entire weight on a tripod of the heels and tail, reducing contact with the icy surface and so reducing heat loss."
