These symptoms can be due to pompholyx or dyshidrotic eczema. Pompholyx primarily involves the hands and fingers and then may involve the feet. The first stage is acute and presents as itchy blisters on the hands, fingers and toes. Then the chronic stage shows more peeling, cracking, or crusting. Then the skin heals up, or the blistering may start again. The exact cause is not known and excessive sweating can be one of the reasons.
I suggest you to get it evaluated from a dermatologist to confirm the diagnosis.
