I went down .5 based on my first pair of Alden shoes which were Leydon lasted. I have no problem wearing thicker socks (e.g. something moderate like the Thorlo light hiker socks) in both my Barrie lasted Alden's and RMW's. I wear a lot of Vans (sz. 8) on the weekends and am unable to wear the the Thorlo socks in those, if that is helpful in anyway.
^ If you have Eagle Rare, then going with Buffalo Trace and Sazerac lets you explore the same distillery. Rittenhouse and Old Olverholt are both classic American rye at great prices. Around $40 for bourbon opens up solid choices like Michter's, Four Roses and Russel Reserve. Enjoy the hunt.
