When replacing and installing the laces you can actually nothing wrong make unless the bands are cut too high from. I'd recommend fundamentally to cut anything, but somehow thread the remaining length, so that the laces can still be used for the next pair of shoes even if necessary (which would no longer be so go when the new Schnürlänge is longer than the old one). For me, the shoe is located now at least as firmly on the foot as before with conventional laces and a node while dressing and undressing is much faster and more comfortable. Granted I am talking about per foot by only a few seconds of time advantage, but everything sits on the first try.
In the package there are a total of 5 individually packaged bags, each with two laces, two closures and two end pieces to wear over the knotted after cutting lace-end. A User's Guide "is also included. A price of 8 euros for the same 5 pair laces in my view is hard to beat because in some other manufacturers at the same price you get only 1 pair.
