For a casual shoe, AE would certainly recommend the two you are looking at. I personally have the Neumok and love it… I am a big fan of Wingtips.
You can also look at the Ridgeway.
Take a look at the site below, they seem to have a pretty good selection of both the McTavish, Nuemok and the Elgins (another casual option). Just note they only carry D widths.
WOW so cheap? I"m a D in all my dress shoes!! Man you're gonna make me spend.. From what I've been reading on the AE website the McTavish does run a little big so go down half a size? I"m a 8 in the fifth avenue
