They are somewhat idiosyncratic shoes; my take:
Very light - my new ones are 208/214 grams for a 45A (narrow) w/o insoles
The soles are *extremely* stiff and of unusually high quality hand laid 3k carbon
Lots of sizes, widths etc
You can specify custom colours and some are very nice (will post pic of mine when I find out how to do it
They are fragile - you can crack the sole easily if you walk too much or rest your foot at lights etc
Delivery times much longer than promised upfront in my experience (8 weeks vs. 3 promised)
Customer care is somewhat sketchy **
I had 2 pairs which fit me well. I like that they are uber stiff and narrow but still leave space around the toes.
On one pair I did maybe 13-15k kms on the other pair way less because I used them when the heel pad was worn out and cracked the sole. --> never ever wear w/o the heel pad. Just received a 3rd pair and will update on how these work out...
Note**: got sent shoes in the wrong custom colours (despite multiple reminders) and with a crack/line on one sole, not sure if only cosmetic, hard to say, but still...
Called the owner, KC, who responded he will rectify both issues. Still, a bit disappointed, let's see how it works out.
