Another vote for Bloch here. I have no idea about ballet shoes but my DDs teacher came with us for first pointe shoes and seemed really pleased with the service and fitting at Bloch. My DD loves her shoes, no discomfort once used to pointe work, so that’s been great too.
Not about pointe shoes but we’ve had mixed experience in Dancia. Other DD came away with great tap shoes (and other items) but awful ballet shoes - her teacher thought we’d bought online (poorly) and couldn’t believe the shoes were ‘fitted’ instore (too long, too narrow - I think it was the only ones they had and wanted to ensure a sale.) 😬 I’ve since been shown what to look for and not just to base on trust/accept any shoes we are sold.
