I didn't purchase this slipper from Amazon but purchased it from the  Orthotic Shop cause it was less expensive. I spent more money on a slipper then I wanted too but I have bad arches and if they helped with the foot pain they would be worth the money. Unfortunately I kept them too long to get my money back from the Orthotic Shop and believe me I tried but after reading so many positive reviews I held on to them with hopes that they would mold to my feet.
The reason for this review here on Amazon is to tell you they didn't and the insole is so hard that after the initial molding they were done adjusting leaving me with slippers that after wearing them for a short time begin to hurt my feet.
IF YOU HAVE BAD ARCHES AND GIVE THEM A TRY BE SURE YOU RETURN THEM BEFORE YOUR 30 DAYS ARE UP.
UNFORTUNATELY I WAS A FEW DAYS OUT OF DATE.
