Adidas Terrex Hiking Shoe, Footwear & Boots Size Chart, Guide & Advice

US Sizes
Adidas Terrex footwear is made using the US sizing system and is true to size - no need to go up or down a size. To ensure the best fit we recommend:

● If you have owned any Adidas before, buy the same size again; their sizes have not changed. Terrex are sized in exactly the same way as regular Adidas.

● Shop using US sizes.

UK Sizes
Adidas's UK sizes have been converted from the US using Adidas's own formula - which we do not believe to be correct. Adidas UK sizes run a half size too small so if you want a UK 8, buy a UK 8.5.

EU Sizes
Adidas's EU sizes have been converted from the US using Adidas's own formula - which we do not believe to be correct. For shoes size EU 36 or bigger, Adidas sizes run 0.7 of a size too small so, if you want an EU 43.3 buy an EU 44. For sizes smaller than EU 36, Adidas EU shoe sizes have been correctly calculated.

Mondo Sizes
Correct as shown below.

On Our Website.....
On our website we use Adidas sizes (even though they are not always correct) because these are what appear on the shoe boxes and the shoes themselves.
