What you read sounds like a reprint of Sonic's origin story from Fleetway's Sonic the Comic, which came out fortnightly in the UK for several years. Sonic was originally brown, Kintobor developed Sonic's shoes to help him overcome his own limits as well as a giant wheel for measuring his speed, powered by the Chaos Emeralds, when the machine exploded, Sonic got his blue colour and super speed, and kindly, frail Kintobor became the evil and rotund Robotnik. I can scan the relevant issues if you want?
