Replacing Hoka ATR Challenger 5 Wide fit insoles

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.

Excellent quality for the price. I'd go as far as saying better than the ones they replaced!

They don't fit inside the trainer

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.

Difficult to size

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.

Don't buy size EUR 39/40

I bought a pair of EUR 39/40 but it didn't fit in any of my shoes of size 40 or 40.5. The insoles are printed 39/40 (24.5-25.5cm) but i meassaured it and shockedly it is actually 27 cm long!! Insoles longer than the just doesn't make sense. I will return it to the shop.
