Shipping & delivery
$25 AUD flat rate shipping on every order, anywhere in Australia. We are a parallel importer: stock is bought at retail overseas and ships from that market straight to you, so allow 2–3 business days handling and 8–9 business days transit (10–12 business days total), fully tracked. The price at checkout is final — GST and any duty are already included (Delivered Duty Paid). We don't ship to PO Boxes or Parcel Lockers.
Returns & refunds
14-day returns. You have 14 days from the date your order is delivered to request a return. Items must be unworn, unwashed, with tags and in original packaging (including the shoe box). Faulty or incorrect items: contact us and we'll normally provide a prepaid return label. Change of mind or wrong size: return shipping is at your cost — no restocking fee. For these returns we'll either email you a return label to post yourself, or arrange return shipping or courier collection — a $10 collection/handling fee applies when return shipping or courier collection is arranged by us, deducted from your refund. There's no fee if you post it back yourself. The $25 shipping fee is not refunded on change-of-mind returns, but it is refunded in full if we cancel your order because the stock turns out to be unavailable. Because these are parallel imports the brand's Australian warranty generally won't apply, so we handle faults ourselves — you deal with us directly. Refunds go to your original payment method within 5–10 business days of approval, in line with Australian Consumer Law.

On Running Men's Footwear Size Guide
On lists all footwear on its Australian site in US sizing. Your Australian size is the same as your UK size, and On puts US only half a size above UK — so a US 10 is an AU 9.5.
| US | UK / AU | EU | CM |
|---|---|---|---|
| 7 | 6.5 | 40 | 25 |
| 7.5 | 7 | 40.5 | 25.5 |
| 8 | 7.5 | 41 | 26 |
| 8.5 | 8 | 42 | 26.5 |
| 9 | 8.5 | 42.5 | 27 |
| 9.5 | 9 | 43 | 27.5 |
| 10 | 9.5 | 44 | 28 |
| 10.5 | 10 | 44.5 | 28.5 |
| 11 | 10.5 | 45 | 29 |
| 11.5 | 11 | 46 | 29.5 |
| 12 | 11.5 | 47 | 30 |

Fit: On recommends going at least half a size up from your street shoe for running. On women's shoes run 1.5 US sizes larger than men's, so a men's US 7 is a women's US 8.5.
