You’re training hard but you want the best out of it so have a look at Enertor products which are endorsed by Usain Bolt.
They have performance insoles and as someone who has had foot problems I can tell you that these really work and as an added bonus they also help to prevent plantar fasciitis which, if you’ve ever suffered from as I have, you’ll know how painful it is. In addition they also do comfort insoles for everyday shoes and you can buy them as full insoles, 3/4 insoles or heel cups to suit your needs.
Added to this you can also buy energy shorts, tops and socks. Click the button on the home page to go to the site to get full details. If you decide to purchase enter the code PTCG10 to get a discount.
