In particular, simple plantar skin itchiness, tingling, small red spots and blisters in localised locations are likely to be caused by foot odour. However, plantar skin can also be caused by sweat blisters, which develop in late spring and summer and heal spontaneously in winter, with a definite seasonal and recurring tendency to have small localised blisters accompanied by itchy symptoms before the skin peels off.
Therefore, the skin on the soles of the feet should be treated before asking a doctor to identify exactly what the cause is, and not to use medication blindly.
