I am considering buying a pair of Allbirds for my senior dad, who is diabetic but without swollen feet.
His feet are sweaty and he lives in a hot and humid location.
I see that Allbirds shoes are lined with wool. Are they then not suitable for my dad?
I know that I should order a pair for him to try on at home, but he does not like shoe shopping in general. Also, I don't live close to him and therefore cannot assist him with the actual process of trying.
