Received mine a few days a go, was s bit skeptical on them as I have been wearing custom orthotics for years (but they are made out of that hard foam) tossed them in my work boots for a few days to see how they would work out. Wow is all I am going to say, from a long time plantar fasciitis suffer(10 years of custom orthotics, massages, stretching, and the next step was going to be surgery), waking up in the mornings is an entirely new feeling lately. I've yet to do a serious hike on them, but so far I am really liking it them. Took me a day to adjust my feet to them, they were a bit tender, but now they feel great. ,
I'll be purchasing a combo set I think here shortly, although, I would prefer to get the full lengths instead of an additional full length/half length, not sure if that is an option, I'll have to check if they can do that, think they said they could when I initially contacted them.
