Skechers Slip-ins Max Cushioning - Advantageous Review

I bought these for work, While on vacation. I've been wearing them for the past week to break them in, They are still stiff and I doubt they will work well to take away the pain my knees endure while standing on the cement floors of the Showroom. I hope I'm wrong. I was surprised that the laces are functional, you actually have to tie them. I thought they'd be just for show. These are nothing like the regular slip-in shoes, they don't seem to have the same soft support. I do like that the soles are flat, they make my walk more stable, and I don't feel like I'm going to fall off the platform.
