Cranberries are chock full of antioxidant, anti-inflammatory and anti-cancer health benefits. They’re also extremely helpful at boosting your immune system. What does this mean for your feet? Well first of all, reduced inflammation means common foot conditions like plantar fasciitis won’t be nearly as uncomfortable. And a higher immune system means you’re less likely to pick up common foot infections like Athlete’s foot, toenail fungus and bacterial infections of ingrown toenails.
