I bought my rainbows because of all the hype. I've been a basic, 20$ sandal user for years, replacing old worn out pairs every couple of years as needed. Friends and family always told me to buy rainbows 'the most comfortable sandal ever' - finally bit the bullet.
What a mistake. These sandals have a 'break-in period' that never ends. I've been wearing these shoes at least twice a week for the last 3 months and they are the most painful things ive ever worn. Walking even two blocks in them is torture. I've developed constant massive blisters on the pads of my feet from them. I think if i manage to develop massive calluses on my feet they might stop being pure agony but i doubt it.
These are a complete waste of money, save your wallet and your feet some pain and avoid this product
