Ski-neakers
From Transformers Wiki
Ski-neakers are footware designed for travel across water. They use the same propulsion method as jetboats, taking in water and expelling it from the back of the sneaker in a jet, thus they're able to provide an effect not unlike skates.
Fiction
Rescue Bots cartoon
Doc Greene invented Ski-neakers and had his daughter and Cody Burns to test them out on the open sea. Fortunately the shoes worked perfectly, however the two kids were threatened by a freak wave, and Doc Greene and Heatwave had to pluck them off the water before it could reach them. Odd Bot Out
