Description
Black Flat Shoelaces 150 cm – Narrow Barth Laces: the smart, understated way to freshen up your favourite dress shoes.
If your best leather shoes are let down by frayed or faded laces, I know exactly how that feels. These narrow, flat black shoelaces are made by Barth in Germany, a family firm many people quietly regard as the finest lace maker in the world. At just a few millimetres wide, they sit flat and neat through the eyelets, which is precisely the refined look you want on Oxfords, Derbies and brogues. This pair measures 150 cm and is finished with tidy metal-tipped aglets that thread first time, every time.
It is a small detail, but a crisp new lace quietly lifts a whole outfit. Because you receive a fresh, even pair, both shoes look their best rather than one smart and one tired – and at this price, keeping your favourite leather shoes looking sharp costs next to nothing.
Why choose these narrow flat laces?
- Made for smart shoes: the slim, flat profile keeps a low, elegant line across the vamp – ideal for formal and business footwear.
- German Barth quality: tightly woven from strong yarn so they resist fraying and hold a knot all day.
- A proper black: the colour is chosen to blend naturally with classic leather, so your shoes look considered rather than corrected.
- Neat aglets: firm tips slide through even tight eyelets without splitting or snagging.
- Sold as a matching pair: two identical laces, ready to fit both shoes.
How to choose and fit the right length
- Count the eyelets on one shoe. A 150 cm lace typically suits shoes with around 7-8 pairs of eyelets.
- Remove the old laces and set them beside the new pair to sanity-check the length before threading.
- Lace from the bottom up, keeping the flat side facing outwards so it lies smoothly.
- Even up both ends and tie – a flat lace holds a crisp bow beautifully.

About Barth laces
Barth has been making laces in Germany for generations, and in the shoe trade the name is simply shorthand for quality. Every lace is woven from strong, colour-fast yarn and finished with proper aglets, which is why a single Barth pair so often outlasts several sets of supermarket laces. I stock them because, put plainly, they are the laces I would happily put in my own shoes.
Caring for your laces
These laces ask very little of you. Brush or wipe away everyday dust, and if they need more, hand-wash gently in lukewarm water and let them air-dry rather than tumbling them. If an aglet ever begins to splay, a small dab of clear glue re-tips it in seconds. Looked after simply, Barth laces hold their colour and strength for a very long time, which is exactly why so many customers come back for another pair.
Frequently asked questions
Are these laces smart enough for formal shoes?
Yes – the narrow flat cut is the traditional choice for dress and business shoes, giving a clean, low-profile finish.
Will they fray over time?
Barth weave these tightly and finish them with firm aglets, so with normal wear they stay neat far longer than cheap replacements.
