I wear Vivo Barefoot Primus Lite all summer, every summer but they are VERY expensive and I need a new pair every year. So, when I saw Freet Flex, I thought I would give them a try as an alternative.
I have to say, I'm converted. I am already a fan of Freet boots but I often find their shoes have a bit too much volume for me. However, I use insoles, usually the Ortholite, which makes them less voluminous over the top of my foot. Once I had put the extra in and pulled the laces tighter, they were very wearable. I have them on most days, all day, for dog walking (in this lovely weather), working, gardening, gym, leisure and casual and find them very comfortable. I have the blue ones and have put the lighter coloured laces in; they don't look particularly 'barefoot' at all and look good with skirts and dresses. I would say they are suitable for just about everything.
They do smell though! I wear them without socks so I suppose that doesn't help. Four days ago, I washed them inside and out and they have since been outside; they still stink! That's the reason for the four stars, not five. They do look a bit like Sketchers as well but I suppose that adds to the 'non barefoot' look. As another reviewer has pointed out, your big toe nails occasionally catch on the toe guard at the front but this seems to get less with wear.
