These are specially made for Essential Flyfisher with metal aglet ends. Plastic ends split. These are made from Dyneema which is the world's strongest fibre - as used in bullet proof vests. They are woven with 27 strands and have no outer coating to disintegrate. Some fancy laces have an inner and outer - usually the outer fails, followed pretty quickly be the inner. This will not happen with dyneema and it is rated at 900kg breaking strain. At first use they are a little stiff, but soon become supple. Best if double knotted as Dyneema is a slippery material.  

Mike Stevens has had one pair for 4 years and they have shown no sign of wear.

These will suit most wading boots, but measure your old laces before you buy.

For example - Simms G4 need the long laces.

One colour only - black.

Come in pairs - Regular - 2 metres; Long (Suits G4 Pro boots) - 2.4 metres.
