I purchased one of these shoe stretchers along with the spray that was recommended to assist in the stretching of leather shoes and have used them on two new pairs of shoes that were just too snug.  My right foot is larger than my left and I needed to stretch the right shoes twice.  I have arthritis in my right hand and I am able to turn the wheel for lengthening and the knob for making the stretcher wider and then reversing the actions to remove the stretcher from the shoe with ease.  You have to close the stretcher back together and then slowly remove from the shoe; this is  trickier and takes more effort than inserting the stretcher into the shoe in the first place.  I haven't used the attachments for problem areas such as bunions and wear size 9 Medium shoes.  High quality wooden stretcher with steel mechanism; appears very durable and well made.  I recommend this shoe stretcher for women's leather shoes..
