The Speedo Tech Paddle is a great swim training aid and will help you to achieve optimum hand position in the water and improve your stroke technique. The hydrodynamic design makes for optimum contact with the water and flow holes improve your feel of the water as your use these hand paddles. Your fingers sit under the latex strap that is tightening by easy pulling for a secure fit.
The placement of the rubber strap won't be idea for all. But otherwise a brilliant product.
After taking a little while to get comfortable using the paddles I now find them quite effective at improving technique and building strength
