Hello ! The picture you have sent is suggestive of pitted keratolysis. This is a bacterial infection. Usually caused in hot and humid weather. Those who wear closed footwear or sweat a lot are prone to suffer from this.
Treatment for this is easy and simple however precautions need to be taken to prevent recurrence.
You can take a direct consultation to know the medicines.
