Anyone wears Church's shoes and can compare these to the Allen Edmonds Chukka concerning sizing? I wear Church's Ryder and Sahara in UK7 F and I am not sure, which size to get in the AE Chukka. Via Google search I found a printable Allen Edmonds size guide (this guide is not listed on the Allen Edmonds website anymore) and there I am between US 7.5 and US 8. Thanks in advance.
