Can you walk around downtown Boston?

Excuse me, I'm curious about the possibility of navigating the bustling streets of downtown Boston. Is it feasible to leisurely stroll through the heart of this historic city, taking in the sights and sounds of its vibrant atmosphere? Are there any restrictions or limitations that one should be aware of when exploring the downtown area on foot? I'm particularly interested in knowing if the streets are pedestrian-friendly and if there are designated walking paths or routes that would enhance the experience. Thank you for your insights.
