Black Microfiber / 3

$169.00 USD

Bont Prostarローラーダービー用ブーツは、軽さ、反応のよさ、熱成形性を備えた設計です。足に合わせて履ける一足を目指しました。

かかとに熱可塑性樹脂を使用しているため、ドライヤーで温めて成形し、10分未満で足に合うフィット感に調整できます。特に足首が細い方や、太い方に適しています。

マイクロファイバー製のブーツに、交換可能なラバートゥバンパー、調整可能な面ファスナー式の上部ストラップ、シューレースを通せる後部のヒールループを備えています。

※このブーツは在庫品ではなく、ご注文をいただいてから製作を手配します。ご注文から4-6週間で発送します。

Bont独自のAnti-Stretch素材は、Kevlarに似た強度特性を備えています。ブーツの外側の層と肌の間にこの素材を組み込み、ブーツの伸びを抑えています。

素材がずれないように外側の層へ縫い付け、ライナーにも接着しています。つまり、Anti-Stretch素材そのものがブーツの構造の一部になります。そのため、Bontブーツは他社のブーツと比べて伸びにくくなっています。

ブーツの伸びを抑える補強素材

Bont Skatesは、安心してお選びいただけます。1975年以来、多くのスケーターに支持され、インラインスピードスケート、ショートトラックスピードスケート、カスタムスケートでは世界最大、ローラーダービースケートでも世界最大級のメーカーへと成長しました。

Bontは、お客様を大切にする姿勢でも評価されています。最高水準の製品をお届けするために、できる限りの取り組みを行っています。例えば、すべてのブーツは出荷前に16段階の品質検査を受けます。

インラインウィール、ローラースケートウィール、フレームは、最先端のコンピューターによる応力解析で、強度と疲労を検証しています。Bontのベアリングは、世界有数の専門メーカーと共同で製造しています。

Bontのすべての製品は、発売前にチームによる厳しいテストを受けます。Team Bontには世界トップクラスのスケーターが揃っています。

Bontのスケートを選べば、市場で最高のスケートを手にできます。

Bontのフットベッドは、熱成形可能なEVAを使用して自社で製造しており、ブーツ製作時にラスト（靴型）へ最初に取り付けるパーツです。非常に軽量で熱成形しやすい特性を保つため、硬度は65A、厚さはわずか3mmに設定しています。

従来のクワッドローラースケートは、ドレスシューズのような形状を採用しています。見た目は美しいものの、足指や中足骨の周辺を締め付けすぎることがあります。その結果、中足骨の間の神経が圧迫され、いわゆる「ホットフット」と呼ばれる、足が焼けるように熱く感じる症状につながることがあります。

Bontは足の構造に沿った形状により、足が自然で効率よく力を発揮できる位置に収まるよう設計しています。また、すべてのブーツが熱成形に対応しているため、ご自身の足に合うフィット感へ調整できます。

足の形に沿った前足部の形状

Bontは、市場で最も熱成形性に優れたブーツを製造しています。45年以上にわたって改良を続けてきた独自の樹脂は、非常に高い剛性を備えながら、比較的低い温度で柔らかくなります。

一部の箇所だけを成形できるスケートとは異なり、Bontブーツはベース全体を成形できます。これにより、現在の市場で最も足の形に沿ったブーツを実現しています。また、ブーツ全体のフィット感を細かく調整し、自分の足に合う履き心地に仕上げることができます。

詳しくは、熱成形のページをご覧くださいをご覧ください。

Bontのクワッドローラースケートは、かかとの形に沿ったヒールカップにより安定性を高め、蹴り出す力をよりしっかりと伝えます。機械的な操作や、ストラップ・シューレースの過度な締め付けに頼らずにかかとを安定させるため、快適性と血行にも配慮できます。ヒールカップ全体が熱成形に対応し、足に合うフィット感へ調整できます。

かかとの形に沿ったヒールカップ

ラストとは、ブーツを製作する際に使う、足の形を再現したプラスチック製の靴型です。

Bontでは1975年からラストの改良を重ねており、その取り組みは今も続いています。多くのメーカーが使う標準的なラストとは異なり、Bontは箱から出してすぐにフィットするブーツを目指して、ラストの開発と改良に取り組んでいます。

ラストの設計

Bontは、他社製品を上回る軽さと強度を誇りにしています。そのため、ラスト（プラスチック製の靴型）の周囲にカーボンやグラスファイバーを手で積層し、内側から外側へとブーツを手作業でつくり上げています。一般的なスケートブーツの製法と比べて非常に時間がかかりますが、この方法が軽さを支えています。

Bontブーツに適した素材を選ぶため、何百種類ものライナーを検討しました。採用しているのは、マイクロファイバー、スエード調素材、Duroliteです。持続可能性と動物福祉に配慮し、ヴィーガン対応の素材を使用しています。軽くて耐久性があり、においを抑え、汗でも劣化しにくいライナーです。

Suede-Lライナーマイクロファイバーライナー Duroliteライナー

内側から外側へ、手作業でスケートをつくり上げる。Bontが受け継ぎ、強い誇りを持つ製法です。他の製法と比べて高度な技術と多くの時間を必要としますが、Bontのスケートが性能面で業界をリードするための大切な要素です。一方で、一般的な製法よりも製造コストは高くなります。

高品質な製品をよりよい形でお届けするため、製造工程の開発と改良を続けています。例えば、カーボンの硬化に使っていた一般的な真空ボックスは、別の方法に置き換えました。現在は、加圧ラッピングなどの方法を採用しています。従来の真空成形では1気圧ですが、加圧ラッピングでは4気圧をかけることができます。

著名なスケートデザイナーであるInze Bontの技術により、手づくりのモノコック構造のスケートを、可能な限り効率よく製造できる生産体制を整えています。

設計への挑戦を、製造工程の革新で支えています。より軽く、より強く、より速く。

ラストの設計、フットベッド、ライナー、Anti-Stretch、カーボンファイバー、アッパーなどの各工程については、下の各セクションをご覧ください。

マイクロファイバーは、軽くて耐久性があり、軽い転倒でも傷が付きにくい素材です。カラーが豊富で、マット、光沢、メタリックの3種類の仕上げから選べます。また、Bontのマイクロファイバーはヴィーガン対応素材です。

マイクロファイバーの外装材

このブーツには、独立気泡の低反発フォームを使用しています。Bontのパッドは水を吸収しないため、濡れた環境でもブーツの軽さを保ちます。また、ブーツの耐久性を損なう原因となる汗も吸収しません。

パッド

Bontは45年以上にわたり、樹脂の開発に取り組んできました。非常に高い剛性を持ちながら、低温で成形できる樹脂を独自に配合しています。また、当社の製造では短い硬化時間も重要です。ブーツメーカーの中で、樹脂を自社開発している企業はごくわずかです。

当社の樹脂は、業界最低水準のわずか60°C（140°F）で軟化します。必要に応じて何度でも再加熱できるため、ブーツを温めて足の形に合わせやすいのが特長です。加熱後は形を整え、冷えて固まるまで待つことで、自分の足に合った形状を作れます。

エポキシ（ポリエポキシド）は、触媒や硬化剤と混ぜると硬化する、熱硬化性のエポキシドポリマーです。当社は、温度と樹脂・硬化剤の組み合わせによって、硬化と呼ばれる重合反応を制御しています。この工程には数分から数時間かかります。

樹脂に加える硬化剤の量は、気温や湿度によって大きく変わります。そのため、当社ではコンピューター制御で樹脂と硬化剤を混合しています。気温と湿度を測定してから、配合した樹脂を供給する仕組みです。

多くのメーカーは、カーボンファイバーにあらかじめ樹脂を含浸させる、プリプレグと呼ばれる方法を採用しています。

プリプレグでは、ほとんどの場合、カーボンファイバーのメーカーが樹脂を選びます。いわば、さまざまな用途に同じ仕様を使う方式です。ブーツメーカー側では、現代のブーツに求められる熱成形性に合わせて樹脂を調整できません。そのため、多くの他社製ブーツでは、熱成形に高い温度が必要です。それでも成形できる範囲が限られることがあります。

ラバー製のフロントバンパーが、クワッドローラースケートブーツの前部を衝撃から守ります。交換時は、ドライヤーでラバーを温めてから、慎重にはがします。その後、瞬間接着剤などの強力な接着剤でバンパーをブーツに取り付けます。交換用バンパーは、左右一組での販売です。

白いブーツに取り付けた黒いBontトゥプロテクター

Bontのアッパーは、ブーツ上部を覆う軽量なパーツです。ブーツに接着し、縫い付けて固定します。通気性を確保するため、アッパーとライナーを貫く穴を手作業で開けます。バックルとストラップを取り付け、足を下方向と後ろ方向へ引き寄せて固定できるようにします。最後に余分な接着剤を取り除けば、スケートを履く準備が整います。完成品として出荷するには、独立した16段階の品質検査に合格しなければなりません。こうして、市場で最高の重量当たりの強度を備えた製品をお届けしています。

このブーツには、ヴィーガン仕様のオプションがあります。

ヴィーガン仕様では、動物性の原料や動物由来の副産物を使用していません。Bontのヴィーガン対応素材には、Durolite、マイクロファイバー、Suede-L（人工スエード）があります。

Customer photo review of Prostar Roller Derby Skate Boots

I got these Bont prostar boots and they fit perfectly snug just like they are custom made for my feet!

Prostar Roller Derby Skate Boots

I love my Bont boots. I will replace my old boots with the new ones. I was waiting to participate in a tournament before upgrading the boots and mounting my plates. Same setup, new boots.

Prostar Roller Derby Skate Boots

The boots were too small even though I measured based on the website’s instructions. I returned for exchange. I did hear back from costumer care but I’m still waiting for my exchange and have had no updates.

Prostar Roller Derby Skate Boots

My boots are working great so far! I accidentally ordered the wrong size initially, but exchanging them was easy. They fit well and don’t squish my toes like some other skates
