Boreal

Boreal produces all its models of high-performance climbing shoes, trail running shoes, hiking trekking, and mountain boots in Spain. Although many processes are mechanized, the footwear remains handmade and this is reflected in the finished product.
Boreal produce everything from high-performance bouldering, sport, trad and indoor climbing shoes, to approach footwear to high altitude mountaineering boots at their Spanish factory.

Sizing systems can vary between brands.  While US to UK size conversion can be fairly straightforward, UK to European size conversion is often rounded to the nearest half-size which is where confusion can arise.  Throw Japanese linear measure and Mondopoint into the mix and it can be quite the challenge to convert from one measurement accurately to another.

As an online company, we value the importance of providing you with the most up to date fit and sizing information to ensure you find the perfect fit the first time.  As such, all our size conversion charts are checked regularly and updated based on manufacturer's guidelines and recommendations.

Think we're missing key info?  Let us know and we'll take care of it.
