Hi

I take a 35/36 - never a 37 & I found some Shimano road shoes which were size 35 & way too small (ie;, Shimano probably make a shoe that will fit you). Your other option is Keen commuter sandals - I got a US size 5 & they fit well (all other sandals are far too big).

to be honest cycling shoes are less of a problem to me than regular shoes - in the Uk because we lack a large Asian market pretty much nothing starts under a size 37!
