I chose the 'Comfort' for my mother, they were the pair that I felt would best suit her. They feature a deep heel to help with ankle stability, a high arch for extra support, great cushioning, and a raise in the front that helps relieve the pain in the ball of your foot.
The inserts took a few hours to get used to, it felt like a big raise, but that's because of all of the support! After 8-9 hours of wear my mother was in love and reported that she hadn't felt any hip or knee pain all day! That's fantastic!
Footminders sell inserts for casual wear, to use in dress shoes, inserts for sports, and 'catwalk' inserts for high heels. They also sell inserts for kids. The inserts are all designed to help align your body and relieve pain.
