What does the ‘speedlace’ system look like? Is it a Boa type thing or just one of those quick-release friction toggles with thin lacers?
Thanks.

Me excellent and yes a toggle thingy works well.

I have a pair of M089s which use the same ratchet system and it works really well. Super easy to replace compared to a Boa system if it goes wrong.

Thanks. Based on that I think I shall purchase a pair 🙂

Yep, as said above, a friction, toggle thingy, looks like this:
(Nothing to do with the ratchet devash)

Shoes are great though, my first foray into a stiffer sole, they work brilliantly with the M785 XT pedals too.
