I have gone through Bakers both times, and they were great. Kyle is a huge asset to the buyer, as he can answer questions, assist with choices. He probably has seen just about every configuration out there, so he would be worth listening to if you have questions/concerns. But seriously, trace your foot and measure it the White's way if you have not done so already. Bakers will fit you properly. Dont assume because you wear a 16 in other shoes, a 16 in Whites is the way to go. Depending on the last, they run TTS or large. Just FYI.
I appreciate the advice - I will definitely do that. I was thinking that since Bakers had 'sizes' they didn't take the measurements. Thanks again for your responses.
