I love these shoes

I have had a long history of problems with my feet and walking since childhood, due to an undiagnosed broken bone. I find conventional shoes uncomfortable because my foot turns over in them. A friend suggested I try Vivo Barefoot, so I sent off for a pair of Primus Lux Mens. As soon as I put them on, I loved them and don't want to take them off. I have had them for less than two weeks, but already they have transformed my walking and are strengthening my legs daily. I can feel muscles being used that haven't done much for years. My damaged ankle is getting much stronger and more flexible. I can stand for longer and my legs get much less tired. The effects are just amazing. I love the feel of the ground beneath my feet. I can't now manage to walk in conventional shoes and have just taken delivery of the Vivo Barefoot Slyde shoes. Delighted!

Not for me

The positives: speedy delivery, nice looking shoes, so much natural room for your toes to spread as nature intended, lovely customer service over the phone.

Why its not for me: i had read the review here saying a draw pin sliced through the sole like butter. I chose to order it anyway. I walked out in them and passed broken glass on the pavement. I was very scared of injury as the soles are so so thin. I felt i had to keep looking down and avoid stepping on rocks, pebbles or broken glass because you justfeel every crack every bump every imperfection on the ground! They are so expensive for what they are, synthetic, rubber and very simple design, no offence to you vivo! I dont understand why its so expensive. The top of the shoes provide no water resistance but this is already mentioned and i believe you water proof it with a product sold on here.

I just want shoes i put on and not think about them. Walking on cloud feel, soft flexible and keeps my feelt secure warm and dry. These did not give me this.

I have to say i found them too wide and i am a woman normally wear EE in width. Mens are wider than women's here. I reckon womens are wide enough for EE.

I am a complete novic of barefoot shoes so maybe someone more experienced in wearing such shoes would find them great.

They were not my first choice though as the plain black ones were sold out.

I now know i need wide naturally shaped toe box, soft flexible sole with padding and lace up as my heels are too narrow.

All in all, get them, try them. See how you get on.
