Do I really need a dedicated travel shoe bag instead of a plastic bag?

Across the reviewers we read, the consensus is that a purpose-made shoe bag holds up far better than disposable plastic for repeat travel. Verified-purchase reviewers consistently cite stronger zippers or drawstrings, water resistance against damp soles, and breathable fabric that doesn't trap odor the way sealed plastic does. For occasional weekend trips a Ziploc may suffice, but for frequent flyers and gym-goers reviewers strongly prefer a washable nylon or polyester pouch.
