Like the title says, these shoes provide good support. I have low arches and I over-pronate. I also have  plantar fasciitis in one foot. I am a nurse and before these I would suffer from a lot of calf pain. I take the removable inserts out and replace them with the New Balance Arch Support inserts. I know it is time to get new shoes when I have calf pain or I start wearing out the heel cup down to the hard plastic. The first pair I had lasted seven months, the next pair five months. My last pair has lasted just under four months. I started having calf pain again and I noticed I have worn the inside down to the hard plastic. Will probably buy another pair as these are the only shoes that help with the pain, but ~$100 for the shoes and ~$40 for the inserts make it really pricey - and the fact that my last pair only lasted four months makes me upset. At least the inserts last for two pairs of shoes.
