Should I size down on the Tabi Boot if I'm between sizes?
Yes — most owners between sizes land on the smaller one after a few days of indoor break-in. A direct 38.5-vs-39 try-both thread shows the larger size produces a wrinkle at the empty toe space, while the smaller size feels tight at first but stretches after a few wears. Wear the snug pair indoors for a few days; if they are still unbearably tight, sell or return them. Order half down if you can absorb the indoor break-in window.
