Swiftfoot Boots is a two-mana equipment that costs one to equip. It then gives the equipped creature both haste and hexproof, making it an incredible way to protect your Commander while still being able to buff them with your own spells. If you’re not interested in any buffing, then Lightning Greaves is also excellent and costs the same to cast but is free to equip to grant haste and shroud instead. Shroud means no one (even you) can target the equipped creature, which may play awkwardly if you have a fight spell (or similar) such as Ram Through, meaning Swiftfoot Boots is the more versatile option while also being more affordable.
