Estimate occasions, not wishes
Begin with the occasions for which the shoes are needed. Count a plausible number of wears over a period you can picture, allowing for weather, workplace requirements and other shoes in rotation. A pair used only for a few events should not receive the same assumed wear count as a daily work pair.
Fit and comfort are requirements before the calculation. A shoe that you avoid wearing may have a low theoretical cost per use but a high actual one. Check the opportunity to try it properly and the seller's applicable return conditions before committing.
Show more than one outcome
Imagine a $60 pair worn forty times: its purchase cost is $1.50 per wear. A $120 pair worn one hundred times costs $1.20 per wear. But if the second pair is worn only fifty times, it costs $2.40 per wear. The higher price is not justified by arithmetic unless the extra use actually occurs.
Add foreseeable care or repair costs where relevant. A $20 repair extending the life of a pair by forty useful wears adds $0.50 for each additional wear, before other costs. Whether repair is suitable depends on the shoes' condition, not on the formula alone.
Keep upfront affordability separate
The $120 pair still requires $120 at purchase. A favourable long term scenario does not make that payment affordable today. Choose among suitable options using both available money and expected use rather than stretching the budget to achieve the smallest projected ratio.
Track use informally after purchase if the comparison matters to future choices. You do not need a permanent tally for every shoe; a few weeks can reveal whether the pair fills its intended role. Avoid making extra occasions or tolerating discomfort merely to improve the number. Cost per wear should illuminate a practical choice, while the purpose remains owning shoes that you can and want to use.
If work requirements change, revise the expected wear count instead of relying on the original projection to justify another pair.
