# Vague hero copy — dev spec
Site: allbirds.com · Priority 2 · Urgent · Effort: Low (0.5-2 days)

## Problem
The hero headline 'Wildly Comfortable. Super Natural.' is abstract and doesn't directly address the visitor's intent to find comfortable, sustainable shoes, leaving them to infer the value proposition.

## Evidence (from the live site)
> H1: 'Wildly Comfortable. Super Natural.' CTAs: 'SHOP MEN', 'SHOP WOMEN'

## Current state
h1: Wildly Comfortable. Super Natural.; cta: SHOP MEN / SHOP WOMEN; notes: The hero copy is brand-focused and vague, not clearly stating the product category or the specific benefit (e.g., comfort, sustainability) in a way that matches search intent.

## Required change
h1: Comfortable, Sustainable Shoes & Apparel; cta: Shop Men's Shoes / Shop Women's Shoes; notes: Use a clear, benefit-driven headline that directly states the product and key value proposition, and make CTAs more specific to guide visitors to the right category.
