1. Toe shape
Look at the outline, not just the word “wide”. Your toes should lie flat without being pushed together at the front.
2. Heel security
Open-backed clogs trade some security for easy on-off wear. A heel strap or adjustable upper matters more if you will walk quickly, travel or use uneven ground.
3. Sole thickness and footbed
Zero drop does not automatically mean thin or flexible. Decide how much cushioning and underfoot structure you actually want.
4. Instep volume
A clog usually gives you less fine adjustment than a lace-up shoe. Check the maker’s measurements and return policy rather than buying extra length to create more volume.
5. Surface and weather
Indoor floors, wet pavement and trails need different soles. Water-resistant leather is not the same thing as a waterproof shoe.
