A size chart only helps if you're using the right one for the right shoe type — and that's where a lot of Alexander Wang buyers trip up, because pumps, sandals, and boots don't always behave identically at the same marked size. This lays out the core US-to-EU conversion, breaks down where fit tends to shift by shoe category, and gives you a straightforward reference so you're not cross-referencing five different tabs mid-purchase.

The Core US-EU Size Chart

Alexander Wang heels are manufactured under Italian sizing standards, so every listed size is EU by default, whether you're buying direct or through a reseller. Here's the standard conversion used across the brand's footwear line:

Treat this as a general reference rather than gospel. It's accurate for most styles, but the next section explains where it can shift.

Do Pumps and Sandals Fit the Same at the Same Size?

Not always pumps generally run tighter than sandals at an identical marked size because a closed-toe pump has zero  alexanderwangg.com for the foot to spread the way an open sandal does. A slingback or ankle-strap sandal in a US 8 will often feel roomier than a pointed-toe pump in that same US 8, purely because the sandal's open design accommodates width variation that a closed vamp can't. If you're torn between rounding up or staying true to your usual size, factor in which shoe category you're actually buying — not just the number on the chart.

How Do Boots Compare on the Same Size Chart?

Boots tend to run closer to true-to-size than pumps, mainly because ankle boots and booties have more structural room around the foot and ankle than a fitted pump does. That said, lace-up styles like the Throttle boot give you an extra adjustment margin that slip-on pumps simply don't offer — tightening or loosening laces can compensate for a half-size mismatch in a way a fixed pump closure never will.

Width Considerations Beyond Length

Size charts convert length, not width, and that's the gap most conversion tables leave unaddressed. If you have a wider foot, sizing up half a size in length is a common workaround, but it's an imperfect fix since it changes heel and toe-box fit too, not just width. Structured, pointed-toe styles are the least forgiving here; strappy sandals with adjustable buckles are the most forgiving, since the strap itself can compensate for width the way a fixed closure can't.

Quick Reference: Which Styles Need Extra Sizing Caution

  • Pointed-toe D'Orsay or closed pumps — size up if between half-sizes
  • Slingback sandals with adjustable buckles — usually fine at true size
  • Lace-up boots — true to size, with lacing as a fit buffer
  • Mules and backless styles — check heel-to-strap distance separately, since there's no ankle closure to hold the foot in place

Final Word

The US-EU conversion itself is simple and consistent across Alexander Wang's line, but treating every shoe category the same is where sizing mistakes actually happen. Pumps need the tightest attention to half-sizes, sandals and lace-ups give you more room to adjust after the fact, and width is a separate problem the chart alone won't solve.Before ordering, check both the size chart and the specific style's closure type  that combination will get you a far more reliable fit than the number conversion on its own.
