If you wanna reference ice hockey for example they use black tape on their sticks so the puck blends into their stick, making it harder for the goalie to see where the position of the puck is on their blade before they take a shot on net. The contrast shit makes sense and I enjoy skating in white shoes, black with gum soles are also super fun.
Also I swear people who wear all black shoes/foxing/soles can get away with being sketchier because nobody notices their feet nearly as much as someone with white/colored shoes.
All personal preference though. I also wear black pants and white/black shirt 80% of the time because they're cheap and they fit perfectly and you have way less to think about before getting a good sesh
