And, you also need to choose shoes with better softness and breathability. If the upper is too hard, it is easy to cause pressure on the toes when walking, making the nails broken, which is not conducive to the recovery of the condition. If the shoes are not breathable, it will cause the fungus to continue to multiply and aggravate the condition. It is recommended to choose suitable sports shoes or slippers, etc. to reduce the breeding of fungus.
