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.

No noticeable difference
I wanted to see if these athletic insoles could improve my speed and agility but I was disappointed.

They do what they promise (in certain extend)
I bought these insoles to mainly use them with my volleyball shoes and help to gain every bit of vertical whats possible.

great product!
Great Product. All the reviews you read about are true you do get up an extra 2 inches at least, but you must have an explosive jump.

Works
It works great. You have to properly follow the directions, put the springbak sole under your shoe sole, then put your shoe sole on top.

um no
These soles do not increase your verticle, I tried them for a whole week, and on average there was absolutly no increase in my verticle jump.

This item was off the heazey. I could only grab rim but with the springbaks I could dunk! It gives you about 4 inches instantly! I would recommend this item for big ballas.
