Great service. My package was delivered 2 days later than expected, but that is probably to blame on international shipping and the Swedish post system. The fact that I got an email immediately after the package was delivered was amazing though! I will definitely keep 21RUN as one of my goto websites when looking for new running shoes.
Strengths
The 20% sale was great! It allowed me to get the exact shoes I wanted for a great price.
Improvements or tips
When I clicked certain links on the websites it would change the language. This is easily changed back, but caused some frustration while shopping.
