Primary Outcome Measures :
  1. Complete cure at Day 29 [ Time Frame: Day 29 ]
    The primary efficacy comparison between S2G6T-1 vs. rest of study arms will be based on the percentage of subjects at day 29 with complete cure of interdigital tinea pedis.mycological cure (i.e. negative dermatophyte culture and negative KOH) and clinical cure (i.e. absence of erythema, scaling and pruritus {scores of 0, each})

  2. Reduction in Tinea pedis SymptomS through treatment period. [ Time Frame: Day 8 ]
    comparison of Patient Assessment between S2G6T-1 vs. rest of study arms will be based on the percentage of subjects at day 8 with achieving decrease from baseline in the total score for pruritus and burning.
