New slides and swollen foot

[slidesnvjkag]

Just bought some new slides. Not too tight, feel comfy. When I wear them one of my feet puffs up under where the top of the shoe runs and it is sore over the toe. They feel comfy when I walk in them.

Is it possible to walk the wrong way in slides?! Maybe they are aggravating an old injury.

Do you mean sliders?

Yes, sliders - one broad bar at the front.

Not in the UK and we call them slides here. They are so light and soft. Got a red patch that turned into a bruise the first time I wore them, but thought it was an injury. This time the same foot has puffed up. I guess they need to go.
