I have some Sketchers sneakers with Memory foam inserts.  Theyre comfortable but the laces keep untying which make for a safety issue for me.  When I saw these no tie laces, I was very skeptical as I worry most about the tension being adequate enough for keeping the shoes on my foot without slipping.

These are made of silicone and are elastic.  They look like real laces which I like. The shoes are just as comfortable with these, as my conventional tie up laces.  I am very pleased.

The biggest challenge is feeding these into the eyelets of a shoe.  Its not easy.  I used a punch tool to get the bulk of the item through the holes. Surprisingly, only one tore to be rendered unusable.

If you're patient enough to install them, then they're definitely worth your time to use them.

No more untied shoes for me.  I was so satisfied with my purchase, I bought additional sets for 2 more pairs of athletic shoes.  The shoes feel like they're tied with conventional shoelaces.  They feel stable and secure.

Definitely, two thumbs up.
