# Competing primary CTAs — dev spec
Site: allbirds.com · Priority 1 · Urgent · Effort: Medium (2-5 days)

## Problem
Two equally prominent CTAs split user intent and delay the path to purchase.

## Evidence (from the live site)
> H1: 'Wildly Comfortable. Super Natural.' CTAs: 'SHOP MEN', 'SHOP WOMEN'
> H1: 'Wildly Comfortable. Super Natural.' CTAs: 'SHOP MEN' and 'SHOP WOMEN' with no subheadline in the hero section.

## Current state
h1: Wildly Comfortable. Super Natural.; cta: SHOP MEN / SHOP WOMEN; notes: Hero presents two primary CTAs of equal weight, forcing an immediate gender choice before product discovery.

## Required change
h1: Wildly Comfortable. Super Natural.; cta: Shop All; notes: Replace dual CTAs with a single 'Shop All' CTA to reduce friction and let users self-select later in the funnel.

## Acceptance criteria
- GIVEN a first-time visitor on the affected page
