What a fabulous thread! Going barefoot a lot has been my guilty secret, considering the advice we get to wear shoes, like, all the time, on diagnosis. It's great to read your experiences and have a looksie at The Foot Collective website.
To walk barefoot in wet sand is just wonderful, and I love to do it. And if I do a wee sprint, I like to do that in firm sand by the waterline. There is something just fabulous about a wee jog barefoot on a beach, in the event I am up to it. Having read you all now in above, I won't feel guilty or anxious anymore and will put the 'always wear shoes' along with traditional diabetic-food advice.
