Hi @Helen_Ward2! Gabby here from the Community Engagement team at Spocket.
It's been about 4 years since you posted this and I do hope that you were able to find suppliers of the footwear you're looking for. I'm responding to this now as I'd still like to invite you to check Spocket out after all the time that has passes since you raised this concern. We have quite a number of EU and US suppliers of footwear that might suit your needs. A quick search on our catalog by tweaking the platform's smart filters will easily give you access to a wide selection of footwear you can choose from.
I'd like to invite you to sign-up for free on Spocket's official website so you can access the catalog and also learn more about what the app can offer you. As well, you can join our official Facebook group so you can interact with Spocket users and other dropshippers to ask where you can find suppliers for the product you need. All the best!
