Here’s my experiences…
I bought a pair of freerider pros that went through fine (delivered on 3 days)
Ordered another pair that wouldn’t go past processing (black kestrel boas). Contacted customer services and got told they were having system issues with 5.10 shoes and was advised to let them cancel the order and try again. The second order for the black kestrel boas also got stuck in processing. I moaned to customer services again and asked why they couldn’t place the order manually. I just got told they they couldn’t do that, have a £10 voucher as a sorry.
I ordered the Kestrel boas in Olive and they arrived within 3 days (and ten sterlings cheaper 😁)
It appears that the system issue is only affecting certain SKUs 🤷🏼♂️
