After walking on a cement floor at work, the next day my knees are killing me, any suggestions as to what kind of shoes to buy?
Soft rubber soles. They will wear out faster but will save your knees and feet. If you stand in one place very long also add a rubber mat to the floor. The more cushioning the better.
I worked at a home improvement store for over a year, with a cement floor. I bought some insoles at Walmart...I want to say they were about $8. Pretty sure they were Dr. Scholls, but not sure since it was so long ago. They were made of thick neoprene rubber...and they lasted me over a year that I worked there. I just slipped them into some Adidas shoes that I didn't mind getting dirty, and it saved my legs a lot of the shock that your feet take walking on such a hard floor...so look for these at less than ten bucks, and you can use just a good ol' pair of sneakers you already have! Good luck to you!! 0=)
