ASOS's customer-care page sets out a three-step process for choosing a size: check how the item fits on the model, consult the Size Guide and product details plus customer reviews, and optionally use the Fit Assistant for a personalized recommendation. Here is the process as the retailer gives it, along with the limits ASOS itself notes — including that the body-measurement chart and Fit Assistant are not available for all items, and that the Fit Assistant is powered by the third-party Fit Analytics.
Blundstone's own guide says its full-grain leather boots stretch slightly over the instep but not in length, and suggests going up half a size for long wear. Here is the brand's break-in and stretching advice, attributed step by step, plus how to check the fit yourself.
Birkenstock lists all its footwear in European sizes, and its US fit guide gives a simple conversion: add 31 to a women's US size or 33 to a men's US size to get the EU equivalent. Width matters just as much as length here, because Birkenstock says its shoes are meant to let toes spread outwards naturally. The brand marks width two ways — with an outlined footprint symbol for Regular and a filled one for Narrow — and prints that symbol on the footbed itself. This guide walks through the conversion formulas and charts, the two width systems with their women's and men's equivalents, the quarter-inch toe-space rule the brand gives for a correct fit, the break-in steps it recommends after purchase, and the checks Birkenstock's own FAQ suggests before deciding between Regular and Narrow. Everything here comes from Birkenstock's official fit and FAQ pages; as with any sizing guidance, treat it as the brand's own instructions and verify the fit on your own feet before keeping a pair.
Darn Tough publishes its own size charts that map sock sizes (XS to XXL) to Men's US, Women's US, Euro and UK shoe sizes, with heel-to-cuff height measurements in inches and definitions of no cushion, cushion and full cushion. Here is how the brand says to use them, and where its guidance stops.
KEEN's own fit guide draws a line between a wide shoe and a shoe with a wide toe box — and it is careful, in the brand's words, not to be a medical authority. Here is the distinction as KEEN explains it, what the brand says roomy toe boxes do, and how the brand suggests checking toe room.
Blundstone stamps the AU/UK size on the bottom of each boot and asks US customers to order in US size using its conversion table. Here is what the brand's size guide says about fit, heel give, toe space, stretch, and series-by-series differences — and how to check the result on your own feet.
ASOS publishes how-to-measure instructions and UK, US, EU and Australian conversion charts for its own-brand women's and men's clothing. A walkthrough of the bust, waist, hips and inside leg measurements as the retailer gives them, plus what to watch for with dual sizes, petite, tall and maternity charts — including conflicting low-hip figures on ASOS's own pages.
How EU, UK and US shoe sizes relate, why no conversion is exact, and how to measure your feet at home — with the men's and women's charts Foot Locker UK publishes, attributed to the retailer.
Shrink-to-Fit™ jeans are cut from unpreshrunk raw denim, so the size you buy is not the size you end up with. Levi's help-center pages give a sizing table that depends on whether you plan to machine wash, plus care steps for raw denim. Here is what the brand says, with measurements in inches and centimeters, and where its guidance stops.
