Run Faster, Jump Higher Guaranteed. Better your 40 yard dash times immediately. Springbak Springsoles are made from the first footwear material to be issued U.S. patents in the category of "Performance Enhancing Shoe Components". Springbak Springsoles feature a "Recoil Process" that returns 80% energy to the wearer by compressing then springing back to original shape. This process also increases your speed, quickness, and strength while reducing fatigue, shortening recovery time and totally eliminating shin splints forever.
Customer Review: seems to work
bought this for my brother. he runs the 400m in high school track and since he started using springbak his times have improved and he says he is less tired after the race... guess it works
Customer Review: awesome for volleyball players
I bought these for my daughter, she playes volleyball for Long Beach State, in fact the entire team wears the Springbak Springsoles since I have recommended them to the trainers. I did not tell her I secretly put the Springbak's in her Mizuno shoes. She had an awesome game, most blocks ever for her, and I noticed she was serving and spiking much harder. I told her about the Springbak's after the match, she was amazed. She reported less shin splint problems and just less fatigues. She was getting 2to3 extra innches on her verticle jumps, which explaines all the blocks for her. We are extreemly happy with Springbak Springsoles and will recommend them to all our volleyball contacts across the nation.
