Problem Fitting

Really sorry but had to return this item as I found it impossible to get them on my feet. They looked the part and I am disappointed that I can't manage to wear them, perhaps something to do with my lack of dexterity rather than the product, (Age 67)

My new best friends!

I’ve been dreaming about shoes like these for a while. I do ultrarunning and was looking for shoes that were light, minimalist, with a wide toe box, good grip, amphibious, wearable without socks, and that would keep all type of debris from hopping in for a ride.

The Primus Swimrun Boots meet all these criteria except the last two: The heal lug’s stiching rubs against my achiles tendon and forces me to wear socks, and the boot is not high or tight enough to keep pine needles and small rocks from jumping in. Another down side is that US half-sizes aren’t available. I would have taken a US 10.5 but had to settle for a US 11, which is a bit too long.

Small drawbacks aside, these are the best shoes that I own, and I have LOTS of shoes. I wear the Primus boots with very light socks and some gaiters, and that combination makes for the best running experience I’ve ever had with running shoes! I can really run free, through pine trails, mud, sand, puddles, rivers, rocks, etc. They’ve become my best running buddies!

Hey Vivo, if you’re listening, great work!

cool addition to the range.

Great all round sports shoe, looks good in the mud, in the sea and on the street!
