The Vibram FiveFingers KSO is the most popular model of FiveFingers, due to its comfort and versatility. KSO stands for "Keep Stuff Out" as it features a thin abrasion-resistant breathable mesh upper that wraps your foot to do just that. They also have the original 5 fingers sole made from razor-siped 3.5mm Vibram TC1 performance rubber.

For a more open-topped breathable model you may want to consider the EL-X for Men or the Entrada for Women

Customer Reviews

The product:

The shoes are amazing, they have a good feel, a good grip, and they have a flexible sole. My advice is get some running socks to avoid blisters and go on the vibram website to learn good running form, there really good for that.

Also, you'll be sort for a week but that has to happen with the transition from ordinary to barefoot running.

Lets speak customer:

1. The customer service here has been taken to the next level. I actually shipped the shoes back 4 times, I asked how much shipping was, and was told was about £4.50. I offered to pay for the next shipping but they still paid for me. All in all that's 26% of the price for the actual shoes.

2. They also use interlink to track you order. I mean, they really track your order, you get shown a map displaying where the actual vehicle is on the map to about the nearest yard. On top of that they arrive next. They hold true to their word (all four times).

3. You get immediate help when needed, within an appropriate time of course. The guy who does it (and I really think it is just the one guy) will go above and beyond the call of duty to guarantee 5 star customer satisfaction.

So, shipping is taken to the next level, it's free and quick. The tracking order has been taken to the next level. Customer service is amazing, single handily too(I presume anyway).

So, I think I'll be buying here again. (Posted on 14/02/2014)

Excellent product, Deborah Cole

Very comfortable, excellent value for money. (Posted on 01/02/2014)
I have a very wide foot and pleasantly surprised they actually fit. I use FiveFingers KSO for mixed martial arts and fencing as it has a flat sole which is excellent for foot work and provides a little more protection than bare feet. Very comfortable, excellent grip, nice to run on grass but a bit hard doing circuits on indoor flooring. The Vibram logo has come unstitched. (Posted on 19/09/2013)

New spring in my step, Mark Slattery

Excellent help before I bought with sizing. Fast delivery and great value.

They really are the most comfortable shoes I've worn. It is like walking round in your favourite slippers. The only drawback is learning to get your little toe into its' slot, but you soon learn to cope with that.

Just wish I had found Born Barefoot and Vibram Fivefingers years ago. (Posted on 08/09/2013)
I purchased the Vibram FiveFingers KSO in black and orange as all black was a bit I'm loving them. They have just enough orange to make them cool, without going any further. They are very comfortable. Piece of advice: I have quite wide and chunky EU45 UK11 feet and they advised me Vibram Size 44. Trust them. These guys know their product and what they are doing. They won't sell you anything just because.
Thanks a lot for your advice and help! Can't wait to test them running, once I finish my adaptation! (Posted on 24/08/2013)

9/10 Fantastic, James Cherrill

Purchased the five finger KSO, found the sizing guide very helpful, fit perfectly having now been worn in. Very comfortable, durable, and wash perfectly in the machine. I found the instant chat feature on the website very helpful, and a small problem I had with the ordering system, was solved and rectified immediately. Delivery was extremely prompt. I would completely recommend both the product and service to anyone looking to purchase some vibrams. (Posted on 12/08/2013)
