Altra Size Chart India: Zero Drop Trail Running Size Guide for Men and Women
Altra Shoes & Sneakers Size Chart
Altra sizes everything in US men's and US women's, built around its trademark zero drop platform and FootShape toe box, a wider, foot shaped front end that most other running brands don't offer. Fit can vary slightly between trail models like the Altra Olympus 2.75 and road models like the Torin, since the toe box width changes across silhouettes. If you're between sizes, consider the next half size up, especially for trail runs where your foot swells over longer distances.

What Kicks Machine actually stocks right now: Men's Altra listings on site run from UK 4 to UK 14, including the Altra Men's Olympus 275 White/Coral and several Lone Peak and Torin 8 colourways. Women's listings run from UK 2 to UK 10, including the Altra Women's Olympus 275 Black/Gray, the Altra Women's Olympus 275 White/Coral, and the Altra Women's Olympus 275 Coral/Black. Sizes at the extreme ends of Altra's official chart (UK 15 and 16 men's, for example) aren't currently listed, so check the full Altra collection before assuming a size is in stock.
Altra is a genuine gap in most Indian sneaker retail, almost nobody else here carries a dedicated zero drop trail brand, which makes getting the size right on the first order even more important since exchanges from smaller Indian cities take longer.
Frequently Asked Questions
Does Altra run small or big?
Altra generally runs true to size in length but wider than most brands across the toe box, thanks to the FootShape design. Trail models like the [Altra Olympus collection](https://www.kicksmachine.com/collections/altra) can feel roomier still, so buyers with narrow feet sometimes prefer their usual size rather than sizing up.What does zero drop mean for sizing?
Zero drop means the heel and forefoot sit at the same height, unlike most running shoes that raise the heel. It does not change your length size, but it does change how your foot sits inside the shoe, so first time Altra buyers should still check the CM column against a fresh foot measurement rather than reusing an old size from another brand.Why is the women's UK size so different from the US size?
Altra labels everything in US sizing at checkout, and the UK conversion in the table above shifts by about two full sizes compared to US women's, which is standard across most running brands, not unique to Altra. Always order by the UK size shown in the KM size chart above to avoid a mismatch.Which Altra models does Kicks Machine actually carry?
Kicks Machine currently lists the Olympus 2.75 trail line, along with Lone Peak, Torin 8, Escalante, Superior, Experience Flow, and Provision models. Check the [Altra collection page](https://www.kicksmachine.com/collections/altra) for the current live range before ordering, since colourways rotate.Should I size up for long trail runs in Altra shoes?
Many Altra trail runners, including buyers of the [Altra Women's Olympus 275 Coral/Black](https://www.kicksmachine.com/products/altra-womens-olympus-275-coralblack-al0a85ru602), size up half a size for runs longer than a couple of hours since feet swell on the trail (via Reddit buyer feedback). For everyday wear or shorter runs, your standard size from the chart above works fine.Can I return or exchange Altra shoes if the size is wrong?
Yes. Kicks Machine authenticates every Altra pair before dispatch and offers cash on delivery plus a standard exchange window, so getting a size wrong isn't a costly mistake. Still, using the CM column above against a fresh foot measurement is the fastest way to get it right the first time, since Altra is sourced internationally and a re-order takes longer than a domestic brand.SEO checklist
