These are awesome! If the shoe is to tight in few more places or one side more than the other, you can put those little inserts on the stretcher and put in back in for that comfortable feel. If the shoe is leather I also use a leather stretch liquid you can usually get from your shoe repair store. . Love my little puppies...Keeps my Dawgs (toes) comfy. Do not hesitate in buying these just add to your cart as you will be happy you did.
