 Speed : FTL (Sonic is his rival, and Sonic is at least FTL in base.) | FTL, speed is complemented by teleportation spamming | At least FTL | FTL+, possibly MFTL (equal to Super Sonic) Keep in mind I believe both Sonic and Shadow could be slow barefooted, however I believe Shadow would be slower while Sonic would still possess great speed, way above pro-athletic in speed.

A pre-canon fact (though could be outdated and moot) is that Sonic's shoes are specially made from anti-friction material to prevent feet-burn and grant additional speed (though still have treads that respond to pause of motion that allows him to stop. Something AoSTH, Sonic the Comic and early Sonic canon says.)

Shadows jet shoes could function similar to Sonic's shoes (given instead of being made from an anti-friction material, simply prevent physical contact with ground with a skating manner) Shadow relies on a skating form to move and force of momentum for motion. Also Shadow is "The Ultimate Life Form" such as immortal, conductor of chaos energy and who knows what other tricks up his genetic sleeves while Sonic's speed is all natual (whenever regarded as born with it or from the "Advanced Non-Concussive Cobalt Effect".)
