Not 'walk', you never walk in boxing. When he- Toney did this as well, among others- would come behind a jab, for example, he'd pull in close, his left shoulder in the opponent's chest. It is easy not to get hit in that spot. His right hand is behind you and you pick your right glove up to block his left, which you can see coming because you are looking right at it. You are also in a very good spot to do what you want to do offensively.
