local wornsoftid = 6530
local BootsId = itemid(BootsName)


if mppc <= softequip and not pzone and boots ~= softuseid and itemcount(softid) > 0 then
	moveitems(softid, 'all', 'boots', 1)
	wait(500, 600)
elseif ((mppc >= softunequip) or (mppc < softunequip and boots == wornsoftid and itemcount(softid) == 0) or pzone) and boots ~= BootsId then
