Sizing Small (ii)

This shoe fits small:consider a larger size

The best guide for sizing your new Freet shoes is to start with your usual shoe size. Think about whether you always take this size or whether you sometimes need to go smaller or larger.

Customer feedback is that this style fits small to size; if you sometimes have to go up a size, it is more likely that you may need to go up a size with this style.

Our shoes are originally produced in EU sizes. All UK sizes are the closest conversion so, if you know your EU size, you may want to consider using this.

Measuring Your Foot

Sometimes as a second check it is worth measuring your foot. Feet can be different sizes so its worth measuring both and taking the largest.

Standing next to a wall place a piece of paper against the wall. Place your foot on the paper with your heel just touching the wall.

Measuring Your Foot
  • The next stage is easier if you get someone else to help do it.
  • Take a pencil or pen and trace the outline of the foot on the paper.
  • Start at the heel.
  • Keep the pen at 90 degrees to the paper, so vertical, see diagram.
  • Don't draw under the foot.
Keep pencil verical
Taking a ruler measure the length of the outline in millimetres. This will be the exact size of the insole you will need. To ensure the fit is not tight add another 5.0 - 10.0 mm to the length. If you wear thick socks then add that thickness to the length.
Measuring your outline

If possible, please work from the EU sizes (the US and UK sizes are nearest conversions to these sizes so will not be as accurate). The lengths and widths are the dimensions of the insole in mm measured as per the picture below:

Great all-around trail shoe

I've had my Calvers for about 150 miles (~250km) now, and both the uppers and outsoles are holding up great. The durability is refreshing after a pair of Altras essentially disintegrated within a few months.

The grip is solid in a variety of conditions, but especially in the mud. It's some of the most versatile grip I've found. However, I have had some slippage on algae-covered bridges/rocks like you might find where I primarily hike in southern Appalachia, though just about any other shoe would struggle on those surfaces. A softer rubber compound might have more grip in these areas, but I'm willing to make that sacrifice for the added durability.

I find the shoes comfortable while also providing great ground feel. For longer hikes, I did find my feet getting beat up, especially on descents littered with small, sharp rocks. Adding the OrthoLite insole was enough to fix this for me, and I assume a rock plate would be a good solution as well.

Overall, I love these shoes, and unless I need a warmer, water-resistant/proof option, they're my first choice when heading outside!

Maybe the best of both worlds

As a long time VFF wearer I'd been using studded fell shoes for winter running. I wanted something that was as flexible as the leading minimalist shoes but as grippy as a fell running shoe. So far on some muddy UK clifftop runs the freet Calver have been very near to the best of both worlds. They don't quite have the stud mud penetration of some leading fell shoes, but the flatter studs on the calver make running on firmer surfaces much more comfortable than feeling the studs. The calver also don't hold mud like many other trail shoes. They are more of a fell runner. Super comfy and excellent ground feel and flexibility. Now they need to get to 500 miles without much going wrong and they might get that fifth star.

Grippy in mud

I normally buy size 41. I got these in 42 and they are nice and roomy. They are a replacement for vivo barefoot shoes that were rubbing a couple of my toes. These are a much better shape for me, a bit squarer across the toes. I can let my feet spread in toesocks with no rubbing, I haven't tried them with correct toes but I wouldn't expect them to fit in comfortably. They also have a more normal lacing system which I prefer. The colour maybe isn't what I would choose, it reminds me of a poison frog. They show up well at dawn and dusk. The grip is really good, I've had a chance to run on soft slippy ground and felt confident in my footing. Also the treads didn't get clogged with mud. I like the spongy free draining insoles.They are very flexible but the thickness of the treads means you don't feel every little stone you land on.

Great Trail Shoe

I run frequently in the Welsh hills, so conditions are general very muddy and wet, but these shoes handle it great. The lugs are solid, but most importantly don’t sacrifice the ground feel I love. They are solid and the lacing never lets me down.
