Under Armour Boys’ Ignite IV Slide

I bought these for my 10 yr old son. He has higher arches and the gel soles are amazing for him. I am concerned about the gel if they will soon smell from sweaty feet but so far so good. He has worn them for hours walking and never complained his feet hurt like some slides that have the “massage” bumps in them or others like his Nike that were just flat and hurt after walking long distances. I will update if they start to stink.
