Review: truly unbreakable - It's made of a very durable material, wow! If it were a little thicker, that would be even better, but I'm happy with the price and its excellent quality.
Review: Best Laces you'll every buy. Period. - I've had these same laces on 3 pairs of boots, and these Thorogood eyelets were the demise of this pair, just ordered another pair for the new boots im getting today, hoping to have the same results!! Yes the color faded. But you expect that being a welder. Still strong as ever even with a slight abrasion. There is a break in period where they are like trying to tie mig wire together, but after that, they tie nice and hold tight. Recommend these to everyone at work with new boots. Best Bang for your Buck!!

## Questions & Answers

**Q: How do I pick the appropriate length for my boot? I don't know the current lace length.**
A: There are boot lace length carts on the internet based on how many eyelets your boot has.  Most lace manufacturers will have this information on their website.  Another way is to use a spare piece of string.  Lace up a spare piece of string cut it were you like the length and measure that.

**Q: are they made in china?**
A: I also checked out whether they were made in China. The are made 100% in the USA.

**Q: Is this for just one or a pair of laces?**
A: This is a pair of laces. It comes with two laces total. One for each shoe/boot.

**Q: I tear an average shoelace every day skateboarding, will these withstand a beating from griptape?**
A: I would be surprised if they ever broke, griptape or not.

### ⭐⭐⭐⭐⭐ Holds up to heavy sparks from grinders!
*by T***E on May 14, 2022*

Most durable laces that can still be tied well enough that I have ever seen! Lasted over two years of heavy sparks and even occasional molten metal from use as a steel pipe fitter/fabricator. Normal cheap laces last a month or two, "durable" laces and the original laces that come with the name brand timberland boots last 3-5 months, these lasted over two years and more than paid in the difference in cost. Still they failed in the same way, dry rot and failure in the underside which never got cleaned but zero damage from sparks so they far outlasted everything. To give an idea of the abuse, my $190 timberland boots only last 12-16 months and my full leather apron to block the sparks at my stomach only lasts a year so these things can clearly take abuse. Worth the money for me most definitely. The main con is the cost, really unless your dealing with sparks or mud these arent worth your money in my opinion, but some people really need laces that can handle sparks and weld slpatter and these work for that surprizingly well. The only real con beyond the cost is the stiffness, they are more difficult to tie but I learned an effective way to tie it with little risk of untieing and easy untieing later. Single underloop to start basically the way most teach to tie shoes, then single bunny ear and pull the otherside all the way through (dont make two ears at the same time, just one), then bunny ear the other side as a double tie and get it very tight. The first bunny ear tightens to the shoe and the second ear tightens to the first ear. This way never has come untied unless the string was left too long and got stepped on, actually these get tighter than conventional laces only doing this way specifically but releasing isnt an issue since pulling the correct string will pull out one loop then pull the other and its untied. The laces do require a very tight tie to not come untied, but doing the separate single bunny ears as described allows for a very tight tie without the shoe itself being too tight. Dunno why but tieing the bunny ears together for a double tie does not stay tied since they are too stiff, and only doing the bunny ears for a single tie as normally taught for tennis shoes doesnt stay either. And this style isnt as effective with normal laces as with these laces either, im on my feet for 10-12 hours a day in these climbing over stuff and climbing inside of pipe and never came untied unless the release string was pulled. Yet my thin laces on my tennis shoes never stayed tied with this tieing style. If you need laces that can handle sparks and can figure out a tie for them since they are thicker these are very highly recommended!
