Since I have to stand all day, I have to be very careful in shoe selection. I wear Brooks padded sneakers or higher quality Asics. For summer flip flops I like Reef brand in the thicker padded soles. Slippers are Acorn with memory foam insoles, those I get from Amazon, the others I get from Zappos. I never get a good price either because I wear either a 9 or 9.5 C and apparently it's a common size and sells out before they go on sale.

I have some low heels in sensitive sturdy styles that I can't wear anymore because it gives me so much pain, same with some low heeled leather boots for winter.

It always needs to be something that feels like a padded sneaker or slipper.
