I really liked these shoes. Overall they just slip on and my only concern was they would be too tight where they would hurt my legs or too loose where they would actually slip off since you don't have laces. My Answer: They are a little closer to the too-tight side FIRST. They are only suitable for durable leather, which takes a bit of getting used to when breaking in shoes. I have used all types of polish and have had no problems with these shoes on any polish. I recommend using a black shoe polish to keep the black tone nice. Shoes are comfortable with insoles. But partial destruction occurs at your toes. You will find that it is very difficult to bend, so I recommend walking around the house for an hour or two for the first few days to really break in the shoes. Once you feel comfortable, you can just wear these shoes and it will be great. ! Another recommendation is to wear only thin socks. I think wearing socks makes these shoes look amazing! However, I will have a problem, if you plan to use them for all occasions, you will notice that creases will appear on the curved parts, but this will happen with any shoe, but they are usually less noticeable with black shoes. Overall, this shoe is suitable for every occasion.
