Yes, in most cases, walking boots should be at least half a size to a full size bigger than your normal shoes.
Why Should Walking Boots Be Bigger?
Feet Swell During Walks – Walking long distances causes feet to expand, so extra space prevents discomfort. Thicker Walking Socks – You’ll likely wear thicker hiking socks for cushioning, warmth, and moisture control. Toe Room for Downhill Walking – Extra space helps prevent your toes from hitting the front of the boot, reducing the risk of black toenails and blisters. Better Comfort & Circulation – A snug (but not tight) fit allows for proper blood flow and reduces foot fatigue.
How to Find the Right Fit
Try Boots on with Hiking Socks – Wear your usual walking socks when trying on boots.
Check the Toe Space – There should be a thumb’s width of space between your toes and the front of the boot.
Heel Test – Your heel should stay secure without lifting when you walk.
Test on an Incline – If possible, walk up and down a ramp or stairs to check for movement.
When Shouldn’t You Go a Full Size Bigger?
If the boots feel too loose – Your foot shouldn’t slide inside, or you risk blisters. If the boots already have a wide fit – Some brands naturally run larger.
Final Verdict
Go half a size or one size up to allow for swelling and thick socks. Always test with hiking socks and ensure a secure but comfortable fit. Too tight = blisters, too loose = lack of support.
Getting the right fit prevents pain and makes long walks much more enjoyable!
