    They don't soak up water; stay lightweight, they shed mud well, they don't come off and provide extra grip as the toes can work as they are designed to be used.

    It stands in my mind as a perfect all-rounder and strengthening tool for the whole body, but especially the feet and calves.

    For completely traditional long distance running on hard surfaces one would be advised to wear a dedicated traditional running shoe, but for off road and assault course in particular the FiveFingers Spyridon MR truly excels.

    The Syridon MRs (Mud-Runners) are a very minimal trail shoe, there’s no rock plate or midsole whatsoever, so demanding, rocky terrain isn’t really the ideal area of use for these shoes, but they excel in wet and soft conditions you often find in the woods (hence the name mud runner).

    It shows Vibram FiveFingers have recognised the massive growth in popularity of obstacle mud races over the last couple of years, and are looking to capitalise on this by providing a shoe that not only copes well in the wet and muddy conditions, but also stays on your foot!

    Though the soles were still functional, clearly they would continue to break down if I proceeded to hike with them.

    Unfortunately, these are going in the garbage even though there is life left in the soles.

    Being advertised as MUD RUNNERS is a joke and pretty much a lie.

    These lugs were based on mountain bike tires so you get 360⁰ of traction no matter what direction you're moving in.

Updates to Spyridon MR

The Vibram FiveFingers presents the Spyridon MR with a new and improved sole unit. This shoe comes with a wider fitting to accommodate a wide variety of shapes and sizes of foot. It is also made to last quite a long period of mud running, while keeping the grip of the rubber in excellent condition. Even after machine wash or hand wash, the rubber lugs still remain grip and exceptional on muds.

The upper is now made from stretchy Polyester, which is a big update for a more rugged look and secure fit. Its sturdy construction allows the shoe to last longer and efficient.

The lacing system is also changed from the usual Velcro straps to the new speed lacing system. It allows personalized fit while keeping it easier to have end security with just a single pull.

The 360 degree lug pattern added into the sole offers excellent grip and maximum movement on all directions. With this design, running on any mud obstacle course or competing in trail race is excellently possible.

Spyridon MR size and fit

The Spyridon MR has a very accommodating size and fitting for a wide variety of runner’s feet. With the new design, the toe box and the mid-foot area is quite wider. The speed lacing system also enhances the fitting as it provides a custom fit tightness that suits the foot.


The outsole features the usual Vibram FiveFingers sole unit, but there is a big difference in the lug pattern as this shoe comes with a 360 degree lug pattern that allows runners to control movement on all directions.


This shoe features a set of midsole just designed for trail running. It has the 3D Cocoon Technology that is molded into the sole to provide lightweight protection against trails, especially on muds. Combined with this is the MEGAGRIP Vibram Rubber of 4mm thickness and the Polyurethane insole with Antimicrobial Drilex Sock liner of 3mm.


The upper of Spyridon MR is made of a set of tougher materials for mud running. The Polyester upper is enhanced with the Polyester mesh lining and a quick-lace closure system. Runners are offered with a more secured fitting as the locking toggle allows a personalized fit in one pull.

The inner part of the upper has the 3 mm polyurethane antimicrobial Drilex nylon that absorbs and wicks moisture away from foot. This technology provides the comfort and cushioning, plus the needed protection on mud running.
