I have worn Naot's Michaela shoes for around 15 years. I especially appreciate the original footbed with all the cork. The replacement foot Bed also ordered with my new Michaela shoes is a disappointment. Are they a cheaper way of manufacturing replacement foot beds? My 10 year old footbeds are disintegrating, which is understandable considering I have worn them for 10 years. The new ones hurt my big toes, the new ridge is uncomfortable and changes the angle of my feet. I was expecting the replacement footbed to be like the original footbeds in all 5 of the Michaela sandal. Can this be fixed?
