J-Heel Spike Shoe Adaptor

Convert your track spikes into javelin or high-jump shoes with this clever device.  It straps around the heel of the existing spike and has fitted heel spikes. 

Ideal for younger athletes who are still growing through shoes at a fast rate, as it avoids the need for specialist footwear.  Also helps multi-eventers avoid the need for multiple shoes.
