Shoe Fit Checker
Bounded footwear fit checks for a specific shoe, person, and intended use.
Should I use this
Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tool inventory
Tools (1)
🟢check_footwear_fit(question, product, bodySignals, interactionSignals, useContext, ...)
Use when the user needs a bounded fit judgment about whether a specific finished footwear product is likely to work for a specific person in a stated use context, including pressure, toe contact, heel slip, width/size questions, dynamic-use problems, keep/exchange decisions, and fit-driven alternatives. Do not use for generic shoe education, style advice, simple size conversion, or medical diagnosis/treatment. When presenting a returned fit judgment, preserve the tool's decision, unknowns, next steps, alternatives, professional boundary, and evidence state. Do not add or strengthen unverified product facts, gait or biomechanical labels, medical causal explanations or diagnoses, or extra size/width/lacing/product prescriptions unless they were independently established as verified evidence in the request. Keep any separately sourced external information clearly separate from the bounded fit judgment.
