For those wondering the difference between new insole/updated insole etc, they posted quite a bit about this and other updates in a recent email…
“However...if you're interested to hear what improvements we've done, here goes:
• INSOLE - A comment we hear is that the cushioning could be better. Starting from Drop 8 we will change the foam density in our existing models to a stiffer, more cushioned version, twice as dense as the original insole. We feel it still qualifies within the "feel great straight out the box" category, without losing the close-to-the-board sensation we're fond of. Starting from Drop 10 we will change all insoles throughout the collection to a brand new version.
• GLUE - Many people prefer to use their own insoles, so as a compromise we've changed the method of fastening the insoles in our shoes to using a softer glue, which makes it easier to rip out (still at your own risk!)
• OUTSOLE - Our shoe uppers are banging! which makes it a bit unfair to our outsole since it wears out faster. To even out this equation we've changed the compound in our outsoles to better withstand abrasion, carefully not to lose the flex and grip we need. Effective on all models.”
