Is ice good therapy for sore feet?

Yes: But do not use for more than 30 minutes at a time.

Sometimes: If a certain area of your foot is swollen and sore, ice would be helpful. If the overall foot and muscles to the feet are sore, heat or soaking in warm water and epsom salt would be a better therapy.

Ice is : Great for swelling it can also feel good if sore. Elevation and heat though is my preference. Soak first in hot water and epsom salt and then elevate. The heat will vasodilate the vessels and allow blood to flow supplying nutrients and making the soreness feel better. The elevation will help allow and swelling to go away.

Therapy: Ice is part of therapy needed to help with swelling. If you properly want to do therapy, the recommended therapy is 15 minutes warm, 15 minutes cold, repeat again, then 10 minutes warm, 10 minutes cold and then 5 minutes ice.
