Close but no cigar

The old school thin ones were solid.

The new style thicker insoles are too much. And these even newer “thin-er” style are just not the same. They’re ok, I wouldn’t recommend em like I used to. I’ve bought no joke probably 30 pairs for myself, family, and to hand out to fellow railroad workers, now we are left with more of the same lame extra cushioning nonsense.

Please go back to the original. I’ll buy a 100 tomorrow.

Hi John,

Thank you for reaching out and sorry to hear that the current M100 style is not working out for you. We do see that you have ordered our thinner T series styles before. If you would like, we can get this pair exchanged for another pair of the T100 or T100 Elite for you, just let us know. :)

Best Regards,
Drew

Another great review

This is pair # 6 for me. Have them in my tennis shoes, running shoes, everyday shoes and even in my birkenstocks. Eliminated some metatarsal pain I was experiencing. Keep up the good work.

Never disappointed

These insoles are amazing, my other insoles lasted over 3 years, probably waited a little too long but they are still in great condition. These new ones are even better, lots of support and great fit!! Working in retail and always on my feet, these were a must have and did not disappoint at all!!

The most comfortable

I have been wearing these insoles for many years and the quality is superior. They hold up well and are easily worn in multiple shoes.

I was not wearing them in my boots which led to plantar fasciitis and learned a valuable lesson. I will not be wearing any shoe or boot without my insoles!

Even my podiatrist recommends these.
