Great shoe for the beach

I purchased my Blooms for a recent holiday to Sri Lanka thinking they would be great for the beat and swimming (for protecting my feat in the ocean). They worked great, the only problem being that sand would wash into them on the shoreline. But it wasn't that much of a problem as the material is very supple and doesn't grind the sand into your skin. They also work well as a regular shoe. In the heat they are great at keeping your feet cool but also protected and they just don't rub the skin at all. The lace system is brilliant. I was nervous about buying them but they where totally work the price.

Great shoes!

Fantastic product! Feels great and natural on the feet--and vegan! This is the first of many purchases!

Miss sizing ... ? possiblity for greatness.

Hi for me its a loss of £60, at best kayak wear not for running

Thinking they would be great if a size up but uncertain?! need the shop to reopen ldn central, or to correct measurements. think I've become an 11 after a certain amount of running in the primus perhaps?... more education on sizing needed or a system to measure up provided online that people can do with tape measurements at home if you have no store open!

Needs different sizing options in my opinion. Bought 10's in the primus 2 years ago. Loved them wore them out.

Bought these, hoping to be a 10 as the main store is closed and couldn't wait any longer before going on holday.

Ended up having to buy another pair of trainers as i've cut my pinky toes open due to rubbing on the first day on the track.
Though they feel actually sizable before you run...

perhaps need 11's after all, wishing the vivo team were quicker with dispatch and open so I could have grabbed sooner!
