Query: comfortable with or without shoes.

i went with the calissage because i read some reviews of other adidas slides saying they were uncomfortable without socks. that was not an issue with this product. the ribs on this slide are a bit uncommon but after one or two wears you can barely tell the difference. i noticed the price went up. i paid 26$ for them and now they are at 30$ but i would still recommend.
