Got it.Never have, this is my first go at it. I did order a size smaller as well. This current size I’m betting I could put 3 pairs of socks on and still have plenty of room so they do seem a tad big. But, I’ll know quickly when I put the size smaller on how those feel.
What you might find is that the smaller ones feel better - perhaps hang onto the larger ones, wear the smaller ones for a year or so, and check your foot size periodically ... after a year, you might need the larger size.
