You don't need to shell out hundreds of dollars for a pair of jumpsoles to improve your vertical jump. Jumpsoles are shoelike exercise tools that you attach to your feet. The device helps keep your heels off the ground, which builds the fast-twitch muscle fibres in your calves.
Make your own jumpsoles for as little as £6.
You need a pair of Crocs or similar shoes, a pool noodle or toilet paper rolls, and strong duct tape for one homemade version of jumpsoles. Crocs are plastic sandals with slingbacks that you can buy online from the company's website. Or you can look for Crocs or Crocs-like sandals in discount stores, such as dollar stores.

Pool noodles or a half-full toilet paper roll are used for the jumpsole's platform. Either material works equally well.
Place the noodle against the front half of your Crocs--from toe to midfoot--to determine how much material you need. Cut two pieces of this size and tape them together using lots of duct tape. The toilet paper roll will need little cutting because it is more or less the correct length.
Tape the two cut noodles or a toilet roll against the front part of each shoe.
Spare Shoe Version
This type of homemade jumpsoles may last longer, but they are more complicated to make. You will need a pair of old (or new) athletic shoes, a knife, a drill, six 1-inch screws and sandal soles that are slightly thicker than the screws are long.
Remove the insoles of your athletic shoes. Cut all straps from the sandals so only the soles remain. Put the sandal soles against the athletic-shoe soles to determine where to cut the sandal. The sandal sole should reach the arch (midfoot) of the athletic shoe.
Cut a small hole over the second or third toe in the athletic shoe. Place the two soles on top of one another. (Basically, you are adding an extra, very thick sole to the front of the athletic shoe.) Put the double-soled shoe on the floor for support. Position the first screw through the hole and drill it through the two soles. Drill the second and third screws in the corners at the other end of the sandal, close to the arch. If you drew lines between the screws, you should end up with an even triangle.
Put the insole back in the athletic shoe, covering the screws.
