These are great, have a waxy feel to them and don't fray like my previous pair.  I have a pair of Johnston & Murphy dress shoes and the laces that came with them didn't last a year.  I didn't want to pay what they charge for laces so I got these and while these aren't nearly as soft and pliable as the previous pair, these are much more sturdy and durable.  And they look really good on the shoes as well.
