ベアフットシューズのアッパー素材を比較：メッシュ vs TPU vs リサイクル

メッシュ通気性と耐久性のトレードオフ

Compare the actual mesh constructions at the eyelets and flex points. Agree abrasion and eyelet pull checks for the sample rather than predicting strength from the layer count alone. For mesh failure locations and staged sample checks, see the mesh-tearing guide.

TPU：隠れた構造的バックボーン

If the design uses TPU film overlays, specify their position, thickness and bonding method. Compare heel retention, flexibility and finished sample mass with the alternative upper; an overlay adds material and cannot be assumed to add no weight.

リサイクル素材：性能≠妥協

再生ポリエステルヤーンはメーカーによって品質にばらつきがあるため、再生アッパーを採用する前にサンプルで伸び復帰率と耐磨耗性を確認してください。.

低MOQ製造業の現実

Ask whether a small test run goes through the same assembly line and QC checks as bulk orders, and compare glue lines and stitching on the first pairs. The material specification guide expands the upper, lining, lasting-board and outsole inputs for an OEM quote.

Q: リサイクル素材の靴は良いものですか？

Recycled content alone does not establish upper performance. Review the material documentation and test the intended construction at its stress points.

Specify the Mesh Construction Before Comparing Samples

Record the mesh construction, reinforcement and acceptance checks in the tech pack. Compare the proposed material on the assembled sample before approval.

If the Design Combines Recycled Mesh and TPU

• 技術資料に織密度を明記し、サンプルで確認してください。.
• If the upper uses recycled yarn, ask which recycled-content documentation covers the proposed material. Agree any ageing, strength or abrasion tests with the supplier and laboratory for that material and intended use.
• Specify any TPU overlay thickness, position and material grade in the tech pack. Check fit, flexibility, mass and bonding on the sample before approval.

工場の現実チェック：リサイクル」がすべて同じとは限らない

For molded components, ask the supplier how the specified material grade is processed and how visible defects are checked. Identify the records needed for your project and agree access before placing the order; recycled content alone does not determine the processing requirements.

結論

Agree test methods and acceptance criteria for the proposed material and construction. Confirm the laboratory scope, specimen, conditioning and reporting requirements; ISO 4892-3 data or a Shore A value is not a universal requirement for every shoe upper.
