Atrocious sizing! I wear size 8 shoes in every brand I own so I ordered an 8. These were massive and I ended up having to order again as Next don’t do exchanges. I ordered the 6s and 7.5s. The 6.5s fit best. Please buy smaller and buy more than one size to try on at home as NO EXCHANGES and currently the turnaround time for processing refunds is very poor. Is a shame because the shoes are actually very comfortable.
