I'm looking to order a pair of Meermins and am hoping someone can help me determine what last and size to order. I measure a US 9D (left) and 9.5D (right) on a Brannock device. I have a high instep and wear a US 9E in AE Park Avenues because of my instep. 9.5D Park Avenues were very tight around my foot because of my instep. I reached out to Meermin and they recommended the Elton last in an 8.5. I'm not sure I agree with 8.5, I think it might end up being too big but have no point of reference or ability to try them on beforehand. If anyone can point me in the right direction I'd appreciate it.
