[SOLVED] How do I weld with this local script?

This LOCAL script turns ur foot on fire.

I have made a local script but I don't know how to weld this object to my foot (R15 RIG) because everytime I use this script the object falls off. this object is in the replicatedstorage where it is activated and put on my foot.

local UserInputService = game:GetService("UserInputService")
Player = game.Players.LocalPlayer
mouse = Player:GetMouse()

repeat wait() until Player.Character

local char = Player.Character
local torso = char:findFirstChild("UpperTorso")
local StaminaVal = Player:WaitForChild('StaminaVal')

local Used = false

enabled = true

InputBegan = true

local function onInputBegan(input,gameProcessed)
	if input.KeyCode == Enum.KeyCode.P and not Used then
		torso.Anchored = true
		local keyPressed = input.KeyCode
		local hum = game.Players.LocalPlayer.Character.Humanoid
		local anim_feet = hum:LoadAnimation(script.Parent.SpinAnimation)
		local current = anim_feet
		current:Play()
		wait(.2)
		
		local x = game.ReplicatedStorage.FireLeg:Clone()
		x.Parent = workspace
		x.CFrame = Player.Character.LeftFoot.CFrame*CFrame.new(0, 0, 0)
		game.Debris:AddItem(x, 100)
		torso.Anchored = false
		Used = true
		StaminaVal.Value = 	StaminaVal.Value + 2

		end	
		end


		wait(1)
		Used = false
		





UserInputService.InputBegan:connect(onInputBegan)
