There are no items that give movement bonuses to Bards, its kind of a let down espececially on the Herald Gaiters, you would expect them to be usable by Bards since Bards ARE heralds in a way XP
so if i wear Strider Boots, Federation Aketon, and Crimson Cuisses as a high lvl rng, i could get +36% movement speed wehn in Windurst! or as a ninja i could wear Ninja Kyahan and Federation Aketon for 37% movement speed in windurst at night. neat!
