I can’t say that these are the most affordable method to save your toes from pain but they seem to have potential. (Costs me approximately $7.50 per pair from a local Duane Reade but they seem to be cheaper online when you buy them in bulk on Amazon; you can probably find them cheaper elsewhere.)
I do happen to have a right flat foot so my back is actually quite misaligned so finding the right shoes tends to be extremely difficult. (Flat feet do not have arch support like most normal structured feet.) This condition had also contributed to a bunion (misaligned toe) and has not healed as of yet.
Comfortable shoes are rare to come by. Due to the nature of my condition, shoes generally fit nicely on my left foot but hurts like hell on the other.
I do regret buying it at that price; I looked at the official price after I purchased it and it seems that there’s a promotion for a $2 coupon that I could have used.
I’ll try it out for about a month or so on various shoes to see if it helps.
