Works on some style sneakers but not others. Depends on how big & texture of the eyelets (what you put your lace through). On one style of shoe it fit great & doesn't feel like it will come out when walking. However, another sneaker of same size shoe it did not stay & pulled out of eyelet quickly.

Pros: has a nice texture on it, not smooth.
Cons: difficult to install -> try using a needle nose pliers to pull them through which should make it easier on your hands.

Bottom line: This will work well for small eyelets & most likely non-metal eyelets.

Let's just start off with how easy to put this on! I was a bit nervous and even wanted to order pliers to install these laces after reading some reviews saying how hard it was and how much their fingers hurt trying to put them in. This wasn't the case me for. The only trouble i had was the very first lace since it was the most narrow and i had little room inside the shoe to pull through the hole. The rest was easy-peasy. Fits my women size 6.5-7 shoes. Great for moms like me who struggle to joggle between 2 kids and having to tie my shoes laces when out. Absolutely love this and will be ordering more for my other shoes. I would recommend to others around my size. I'm not sure if this will work well for bigger feet due to the tightness of the lace. I had to really stretch the lace and use a bit force to put my feet in but once it is in it feels nice. Just the right snug for me. Big feet might have some trouble.

My son hasn't mastered lace tying yet so and the pair of sneakers I got them for have light up soles in different colors. His we got the rainbow set. The colors we received are different than the official product photos but are still colors we're happy with. Since they are varying lengths we couldn't put them in the exact order we wanted. You ROYGBIV adherent people know who you are! His pair of shoes had only 5 eylets and it was too tight with trying the dark blue on top so we only used 4. My 7 year old was able to put his shoes on easily, there is enough stretch.

These are tricky to install with trying to use pushing and pulling through on your own. A stiff blunt ended tool helped. Be careful as you could poke a hole. This happened to us but I think it seems to work okay anyway.

Great product. Works really well. Here is a tip if you have to remove them, as they are really hard to get out if you need to adjust for size. Get a pair of needle nose pliers (shown in picture). Grab the entire end if the lace then push through the eyelet in the sneaker. You will be able to grab the wns and pull them out.

I bought these for my tennis shoes for convenience and because my dog chewed up my normal laces so I needed something new either way. I wear a Men's 13, and this could easily work with up to a Men's 15. I was skeptical because of how large my feet are, but they exceed expectations. Actually, it came with extra laces (or more than I needed) and the largest one that's supposed to go on the bottom is actually too big (and again, my feet are the largest that these are approved for) so I just took all of them except the bottom one and worked my way up from there. If you're a size 14 or 15 in men's, you may want to start from the bottom. They flex really nicely and hold the shoes on snug. I tried violently kicking my shoes off, and nothing happened. They will stay on unless you're trying to get them off. They come off easily if you use your other foot to kick it off or your hand. I really don't know what else to say about the product. It gets an A in my book. I guess the only neutral thing is that they take a while to get in, depending on your shoes. But once they're in the first time (took me 5 min or so) they're in forever.
