These insoles may not be orthotics but in certain sneakers they work so well. A few sneakers I thought I could not wear all day, with these insoles I have changed my mind about the sneakers I wear to work and I'm a barber standing up most of the day and my feet mustn't hurt. Thank you 💈💈💈 yeezy comfort in all my sneakers just figure out which inserts work for what shoe your wearing that day as mentioned the thickness does matter and will affect the tightness in some, and be perfect in another
