Ultra Boost Inserts

The reviews got me and i thought i was going to love these but unfortunately they’ve been no good for me. Its hot outside and they do not stay on throughout the heat. I was not doing anything strenuous or working up a sweat and they still did not stay stuck and the glue began to pile into little balls maybe my order was defective but no way to know as a first time user. Alot of money to spend to be unable to use so i am feeling very upset.

Terrible Product not right and they wont refund if not looked inside which is impossible surely!

Too large even tho followed the size guide and so uncomfortable, they do not stick properly either, waste of money.
