Frequently Asked Questions

Everything you need to know to keep your pace and hit your goals.

How do I choose the right running shoe for my gait?

We provide a detailed size and fit guide on each product page. If you have a neutral gait, stability needs, or require extra cushioning for HIIT sessions, our product descriptions specify the best use case for every model.

What is your return policy on worn performance gear?

We offer a 30-day 'Run-In' guarantee. You can test your gear on the track or road, and if it doesn't meet your performance standards, you can return it for a full refund or exchange, even if lightly used.

How long does shipping take for domestic orders?

Standard shipping typically takes 3-5 business days. We also offer expedited 2-day shipping for runners who need their gear before an upcoming race or event.

Do you offer international shipping?

Yes, Interval Running ships to over 50 countries worldwide. International delivery times vary by location but generally arrive within 7-14 business days.

What payment methods do you accept?

We accept all major credit cards (Visa, Mastercard, American Express), PayPal, Apple Pay, and interest-free installment plans through Klarna and Afterpay.

Are your apparel materials moisture-wicking?
