361° describes the BOUNDAI 6 as having a widened last. That is useful information for someone looking for more room around the toes, but it leaves a practical question: what can a shopper establish from the specification before trying the shoe?
A shape description needs its own context
On the manufacturer’s Feather Flow page, the wider-last description sits alongside a jacquard upper, toe-area perforations and reinforced yarn in selected zones. The same page describes an asymmetric midsole profile and a CQT QU!K midsole.
Those details describe different parts of the shoe. The last concerns its underlying shape; the upper and lacing enclose the foot above it; the midsole profile describes the structure below. A wider-looking sole in a photograph does not, by itself, measure the space available inside the upper.
The official description does not provide a numerical width designation or internal forefoot measurement. We therefore do not label this model 2E or 4E, or promise that it will fit every wide foot. That would add a level of specificity absent from the source.
Read the photographs as views, not measurements
The product gallery gives each available colour its own side, angled-pair, heel and outsole photographs. The pair view helps show how the forefoot narrows towards the toe; the rear view shows the heel shape; the outsole view shows the rubber layout. Use them together instead of judging the whole shoe from one side profile.
The Sprout specification identifies a full-length DIAMOND GRIP rubber outsole and a 40mm heel stack. Rubber coverage and stack height are construction details. They are not evidence of a particular wet-grip result, measured width or personal comfort rating. No RunningArea wear-test or on-foot fit photographs are available for this model yet.
The size chart is model-specific
BOUNDAI 6 links to the brand’s EU size chart. It should not be replaced with the chart used by another 361° shoe. For example, its EU41 row is US Men8, US Women9, UK7 and Brand CM25.5. Read the column heading as carefully as the number.
The brand asks customers to refer to foot length, while the CM column remains a size reference rather than an internal shoe measurement. It does not tell us the precise space around an individual runner’s toes or instep.
Before ordering
Check the selected colour and available size, compare its labelled row with your current shoe and raise any uncertainty before purchase. If you need a documented width code or a measured interior dimension, the evidence on these pages cannot supply it. Our description keeps the manufacturer’s widened-last wording without turning it into an unsupported fit verdict.
