Try using an insole. If you have recently changed your footwear then it might be the cause. Try keeping your sole of your foot on an ice pack for 15-20mints multiple times a day. avoid standing for long times.Avoid going for walk atleast for few days. Along with it you can go with calf stretch. -You need to stand at the edge of a step and then lift your body up . only your toes and some portion of your sole should be in contact with the step. Same way come down slowly until you feel a stretch behind your knees . -In sitting position with one hand pull the heel and with other hand pull the toes in opposite directions. maintain this stretch for 15sec repeat for 5times 2-3 times a day followed by ice application to the sole or you can roll a frozen bottle with the foot. -Move your ankles up and down side to side and rotate in clockwise and anticlockwise directions. - If cold is increasing your pain then dip your foot in a warm water with pinch of salt.

proper protection of soles. Rest is required. icing multiple times a day will help. If still the pain persist you can do an ultrasound therapy at your nearest physio center or get checked by an ortho doctor.
