How did I not know about this amazing gadget?! It’s a game changer for sure. I used it overnight and already can feel a difference in my shoes. It’s a smart design that allows you to adjust the width and length as needed and includes accessories to target particularly problematic areas. I will say the sizing is off. I purchased a women’s medium which stated it fits sizes 6 1/2 to 10. I’m a solid size 8 and it barely fit in my shoes and actually caused the heel area to become loose which was NOT the objective. Other than that, it’s a great product, good quality, easy to use. It is a bit expensive and there should be a more economical option for buying a pair. I bit the bullet and bought two because I just can’t be bothered with stretching one shoes at a time. Overall I’m pleased and excited that I’ll be able to wear these sneakers comfortably! For me the total stretch so far has been less than a half size but I’m confident that the longer I use it the more they’ll stretch. I didn’t even bother with the spray I bought because they’re clearly stretching fine without it.
