I have been using the yellow padded Samurai insoles for at least 1 1/2 years. I have flat feet and were orthopedic plates for my feet go over 40 years. I switched to these and have had no problems. I highly recommend these inserts if you have flat feet.
Having very low arches and wide feet have made getting comfortable Women's shoes difficult. This has led me to sore feet, legs and back followed by tossed shoes. I found your product and started with 1 pair of Samurai insoles for my walking shoes which provided me a level of support I haven't had since using custom orthotics and they were more comfortable. I now have Samurai insoles in my dress, casual, and sporty shoes and will be buying another pair for my new Dr. Marten boots! Thanks for a well made, reasonably priced product that saves my feet and my money!
Just bought my 2nd pair of Samurai Ninja insoles and will use no other.
After dealing with the pain of walking in shoes with no support I found the Ninja insoles and they have been such a blessing, no more heel pain!!! The best part is my feet don't start aching after 30 minutes of walking. Buy them, you won't be sorry!
