Softness is not the same thing as support
A soft shoe compresses readily under load; a firmer one resists compression more. That sensation does not describe the entire shoe. Base shape, upper retention, sole geometry, and the footbed contour also affect whether the shoe feels comfortable and predictable. A soft shoe can have a broad platform, while a firm shoe can still fit poorly.
There is no universal softness setting for plantar fasciitis. Advice to choose cushioning should not be read as an instruction to buy the most compressible sole available. Nor does a firm feeling establish that a shoe is supportive in the way your foot needs.
Compare movement, not just the thumb-press test
Pressing a thumb into an insole mainly tells you about that small area under a brief load. It does not reproduce your full body weight, your walking step, or the way the heel is held by the upper. Use an actual fitting to compare the complete shoe.
Stand, walk slowly, and make a controlled turn. Notice whether a softer candidate allows you to settle comfortably or feels difficult to balance over. In a firmer candidate, distinguish a reassuringly consistent platform from uncomfortable pressure. Neither sensation should be dismissed because someone has told you that soft or firm is always correct.
Choose the tolerable middle ground for your routine
If your current shoe feels harsh, try a different cushioning approach without abandoning secure fit. If it feels excessively yielding, compare a more consistent platform rather than automatically moving to the least cushioned option. Small, purposeful changes can make the result easier to interpret.
Consider where you use the shoe: slow indoor movement and a longer outdoor walk may expose different preferences. The NHS recommends suitable cushioning and support as part of self-care, but that does not establish a particular foam firmness. Ongoing or worsening heel pain deserves assessment rather than an endless search for a softer or harder shoe.
