Comparing the sizes of Topo and Altra is very interesting.

They have almost similar sizes with one of them offering a couple of extra sizes for both men and women.

Also, some of the size numbers in Topo and Altra are different, however, the length in cm or inches are the same.

That is why we have included, the length of the shoe in cm (inches) along with sizes for each country like US, UK, EU…

This helps standardize the sizes and you will be able to tally the sizes based on an actual length and not some arbitrary number.

Do Topo Athletic Run Bigger Or Smaller Than Altra?

Most of the sizes of Topo Athletic are the same as that of Altra. However, there are a couple of them that varies.

First of all, some of the sizes that are available in the women’s version of Altra running shoes are not present in Topo Athletic running shoes.

In the men’s version, the situation is the opposite. Some of the sizes that are available in Topo Athletic are not present in Altra.

There is an anomaly with the size 44 (EU) of Topo Athletic and that of 44.5 (EU) of Altra. Lengthwise both are similar, however, the numbering is different, and also, this is the last size that is available from Topo Athletic in the women’s version of the shoes.

However, the interesting thing about this size is that they are represented by the same numbers for Altra and Topo Athletic for the US and UK regions.

A similar anomaly exists for the men’s version of the shoes also. The 47.5 (EU) of Topo Athletic is equivalent to the size 47 (EU) of Altra s both of them have the same length.

But, for US and UK regions, are represented by the same number for both the companies.
