SPRINT REVOLUTION POWER SOX (COMBO PACK includes Small + Large Pair)

Sprint Revolution Power Sox, these are resistance-training socks used to increase drag on the feet and lower legs, forcing the swimmer to produce more propulsion while maintaining race-specific mechanics.

Power Sox are typically used for:

• Acceleration work (15–25m efforts)
• Power-endurance sets (25s and 50s)
• Race-pace training while keeping stroke mechanics closer to normal swimming than some larger drag devices
• Kick and breakout development

The Sprint Revolution Power Sox package includes both a small pair and a large pair, allowing swimmers to progress the resistance level depending on the training objective. 

• Small Power Sox
  • Higher velocity work
  • Race-pace swimming
  • Technical sprint work
  • Contrast sets (Sox on → Sox off)
• Large Power Sox
  • Maximum power development
  • Starts and breakout work
  • Underwater kicking
  • Short acceleration efforts (10–25m)
  • Strength-focused sprint sets

The progression I would typically use with elite sprinters is:

1. Large Sox for force production.
2. Small Sox for power-speed transfer.
3. No Sox for race-speed execution.
