Women's Footwear Size Guide

Measuring tips

Take your actual body measurements as they are more accurate than measuring over your clothes or shoes.

Feet: Use a ruler or tape measure to measure your foot (from the heel to the tip of your longest toe) Be sure to measure both feet.

Many people have feet of different sizes. Fit to the larger of the two.

Remember, feet can expand over a quarter size during a full day's walk so ensure you get the right fit.

long distance perfect

Bought two pairs one G20 and one G30. Cant seem to get G30 anymore. I used the G30 on the Camino 2015 and the G20 on another camino 2016. 800km each. Still using the G20. Got my moneys worth. v. good

Don't waste your money.

I had been cutting an old foam roll mat up to use as insoles. Each time I did the insoles I'd made lasted about a month before becoming useless. I weigh 12 stone and am on my feet in walking boots for around 8 hours per day.
I bought these Grangers insoles hoping for more longevity and more comfort.
Comfort wise there is no difference between these and a bit of old cheap foam mat. However, the FOAM MAT lasted longer! !
Within a week the Grangers insoles had compressed permanently to wafer this rendering them utterly useless.

Great product

These provided just the right extra fill to a pair of boots that had stretched and become too loose for my feet. Highly recommended as comfortable, not used them for long so not sure about durability.

Great insoles!

These soles are great, they fit into my boots perfectly without any adjustments! They make my shoes very comfortable to walk in.

Happy feet

Since purchasing my new G20 trek insoles my life has dramatically improved. I feel as though I'm walking on heavenly candyfloss and even sleep whilst wearing my boots. Grangers are the luxury of choice for this mountain ranger.

Just the job

Bought to improve the fit on walking shoes. They feel good with more support than the standard insole supplied and at only £5 in the sale these have have been a very good purchase.

Bought as replacement insole for walking boots

I would not recommend this product. I bought them for a replacement set for my berghaus walking boots. I used them for 1 week whilst walking Hadrians wall, I could actually feel the plastic surround around the gel heal pad. I threw them in the bin as soon as I finished the walk, maybe ok if you were just going for a stroke around the park but not up for long distance walking.
