Plantar Faciatis. How i can cure this?

Your symptoms sound less like classic plantar fasciitis and more like a combination of forefoot overload and lateral foot stress, especially since the pain is not in the heel and your right little toe hurts after play. Even though Asics Gel Kayano is a good stability shoe, it can still cause issues if the toe box is narrow for your foot shape or if there is overpronation with lateral push-off, which puts stress on the 5th toe and metatarsal. Try ensuring adequate toe space, avoid tight lacing near the forefoot, and reduce high-impact play temporarily. Gentle foot stretching, calf stretching, and avoiding barefoot walking—especially after sports—can help. If pain persists or localizes more to the outer foot bone, an X-ray may be needed to rule out a stress reaction.
