A response from schuh:
I appreciate you taking the time to get in touch with us regarding the price difference between certain sizes of the Doc Marten 1460 boot. I can confirm the reason for the discrepancy in price is related to how we categorise product when it is purchased into the company. Different size breaks are attributed different line codes within the company and can be discounted differently due to popularity when it comes to sale periods. I apologise if this was not explained correctly when you communicated with our social media team. We welcome all feedback both positive and negative and I can assure you this has been passed onto our Buying Team.
So as far as I can tell, schuh aren’t deliberately overcharging women, just accidentally overcharging them. I’ve replied to ask if this price gouging is to remain a permanent fixture.
