Yep I've got a pair of SM Lites, no great problems with the laces except that the solid tags at the end of the lace (must be a name for it)are splitting making it harder to re-thread after cleaning my boots.
I got SM 9 Guides when they came out some years ago, they nearly crippled me even after sustained attempts to crush my feet into their shape. However, to this day I carry the laces from them in my sack as spares.
Yeah Mark, you're not alone mate!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Mine munched their laces in extra quick time indeed,,,, WEIRD!!!!!!!!!
Been fine since i changed to Yachty string,, its good, & just alter the laces every now & then so they don't wear on the same spot all the time. You only need to pull them through a few milliletres to a fresh spot.
My troubles are way beyond laces though,, wish it was only the laces that were gone on mine!!!!!!!!!!!!!!!!!!!!!!!!!!!
Me soles are falling off after only a very gentle 7 months, no mountains, no ice, no abuse at all. Unreal!!!!!!!!!!!!!!!!!!! Very disappointed as i love them to bits!!!!!!!!!
