Militia or pompholyx. Confirmed diagnosis can be made after visual impression. U wear shoes daily for 12 hours that can produce or aggravate these type of lesion. So avoid this. Apply combination of calamine and zinc twice daily for 7-10 days. If u have irritation u can take tab Atari 25 mg at bedtime.  If they're not responding consult dermatologist.
