Sizing FAQ's

Sizing

Can I trim the insoles down to fit my shoes?

Yes! The insoles are designed to be trimmed down at the forefoot. Please use your current insole as a guide for cutting the Enertor insole down using a sharp pair of scissors. They need to sit flat inside the shoe.

What size should I order - I'm a half size?

It depends on your footwear. There are always slight differences between shoe brands and as a guideline - generally speaking if you are a UK 6.5 you need to order size UK 7-8. If you are a 8.5 then you may need to order a UK 9-10 and so on. If in doubt, measure your current insole from your footwear and compare to our insole sizing below. You can always trim the insoles down to fit your shoes if necessary - please ensure they are long enough and wide enough to work in your shoes:
