There is no denying how your walk communicates your level of confidence and how you are perceived by other people. A confident walk — aka swagger — is a clear, non-verbal invitation, always open to be interpreted and investigated.
Your steps should show confidence and even if you are a little unsure of yourself, always appear calm and collected when walking anywhere. Usually, it encompasses a subtle sway in your shoulders, a solid stance, and a consistent, rhythmic pace.
Swagger is not doing everything with super exaggerated movements and trying to impress people. Going to a cool, structured tempo that gets heads turning without you looking like you are trying at all.
Standing tall, shoulders back, chin up — the secret to walking with swagger is great posture. Someone with a confident stride is attention grabbing and this kind of movement indicates that you are comfortable in your own skin, and that is sexy.
Having swagger is not the same as being an arrogant bastard. You do not strut to make others out of fear trip, it is not to garner unwanted attention on the runway. Really it just moving through life as if you are confident and self assured.
The trick is to be subtle and as fluid as it naturally flows, do not be forced. People will want to have you in their presence when you are confident in your walk.
The first impression is made with confidence and it comes from the way you walk, even before you say a single word. If you walk intentionally, just your body language can command the attention you want and prepare the stage for good interaction.
