Great shoes!

Bought these for my 13 year old son who has been wanting them for some time. He loves them. Wears them all the time as well as for running. Great on all kinds of terrain from rocky to muddy as they have a reasonable tread on them. Feel reasonably sturdy so shouldn’t wear out too quickly.

First Vivos

My first pair of Vivos after a friend, having several pairs for years, keeps going on about how good they are! After trying his I ordered a 10 in red (best colour for these I think), but actually needed the 11. Customer service were really good in swapping my points and sorting the return so I could order the new ones. Took a bit of getting used to, and found the loop for the laces above my big toe joints rubbed to begin with, but this has gone as they bedded in. Impressed, and feet actually quite warm even in winter. Started running gradually in them to get used to the change in style - calf muscles do get quite sore running with a fore strike style! Will still have normal shoes, but am a bit converted and looking to get my next pair - walking boots I think next...

Very comfortable

Very comfortable and light. It didn’t take long to get used to the feeling of a zero drop sole. The feeling through the shoes is great, too.
