When I leave the water sometimes or log into the game, it causes the "weightless" effect of the leggings to apply to my character, acting as if I am hovering in the hair, and unable to go up and down. The only way to fix this in the game is to kill myself or go back into the water and remove the leggings before leaving the water.
While I could not replicate your exact issue, with it making you hover in the air on land, the implementation of it was indeed faulty!
Should be fixed in 2.7.9
Neoforged 21.0.150 Aquaculture-1.21-2.7.8
