Product Customer Reviews

Just bought a pair and they are great Good value /Quality!!
I believe this insoles is not suitable for running shoes. Size is not exact, need to cut it by scissors in-order to get it fitted. Didn’t serve my need.
Great product. Good price
Work really well. Very good price
As Hoka do not supply any parts a such, I was disappointed that the insoles in my otherwise excellent ATR Challenger 5 wide fit were starting to degrade after 300 miles or so and lose their structural integrity. In short working back towards my heel on one foot which will cause blisters etc if it gets any further. The shoes are still in great condition, very little wear and luckily Hoka cleverness is all in the shoe and not much in the insole. These are a very good replacement, so far very comfortable and slightly more firm than the originals which bodes well for rigidity. There was no need to trim anywhere so far, so good and the largest size was fine in my 13.5 UK shoe. Hoka do size up slightly smaller in my experience. All good in the hood.
2nd pair purchased, extend life and comfort of shoes. Would definitely recommend
Excellent quality for the price. I'd go as far as saying better than the ones they replaced!
The trainer and the insole are the same make, which made it disappointing that the size 10.5 insole was to big for the 10.5 trainer. I've trimmed them with scissors to make them fit, but it seems a waste.
Had to cut them to the size but well worth the price. Extremely comfortable.
I had high expectations for those but they didn't fit size 9 so I will return once shops reopen.

Comfortable but didnt stop the pain in the ball of the foot, need to think of other ones.
I am happy with those products, of course I recommend to everyone. Thanks.
My old boots feel better than ever!
Tried to cut down but was difficult to get a good fit and I ended up getting blisters from where they rubbed. Am sure they would be fine if you could get an exact size or there was an accurate cutting guide printed on.
quality ok but not very comfortable
