Nike Alphafly 1 對 Saucony Endorphin Pro 3：邊款碳板競速鞋值得入手？

引言

雖然 Nike Alphafly 1 如今已屬稍舊的碳板競速鞋，但它仍然與 Saucony Endorphin Pro 3 直接競爭，兩者都位列市場上最佳競速選擇之列。真正的問題是：值得去搜尋較舊 Alphafly 的減價貨，還是直接入手較新的 Saucony？我們曾穿着兩款鞋跑過馬拉松並創下個人最佳成績，而答案並不如價格標籤所顯示般明顯。

規格與構造

從帳面數字看，兩款鞋有實質差異。Endorphin Pro 3 的前後掌落差為八毫米，而 Alphafly 1 則為四毫米。重量方面亦以 Saucony 佔優：UK 9 碼為 217 克（7.7 安士），Alphafly 則為 234 克（8.3 安士）。

兩者的構造都遵循預期的超級跑鞋配方。Alphafly 1 採用 Atomknit 鞋面配 ZoomX 中底，這是一種非常柔軟且回彈的 PEBA 基泡棉，前掌內置 Air Zoom 氣墊，並配全掌碳板。外底前掌有實心橡膠覆蓋，後跟另加兩條橡膠，前掌厚橡膠層可提升耐用度並保護氣墊。Endorphin Pro 3 則採用極輕量網布鞋面、PWRRUN PB 泡棉（Saucony 自家的 PEBA 基中底）、全掌碳板及 Speedroll 搖擺幾何設計。前掌與後跟的橡膠覆蓋不俗，中底鏤空則有助減輕重量。

貼合度與尺碼

The Endorphin Pro 3 fits perfectly true to size, and one tester even ran the Chicago marathon in a brand-new pair straight out of the box with no issues. The Alphafly 1 is trickier: its raised arch caused real discomfort during the first few wears, and the shoe feels a bit tighter and less forgiving overall. True to size is still the right call, but note that going half a size down leaves your big toe bumping into a small raised plastic section at the front, so be careful if you size down.

腳感：彈跳對比順滑

This is where the two shoes genuinely diverge. The Alphafly 1 feels active and slightly intrusive in a good way: extremely bouncy, with a strong pop off the forefoot from the Air Zoom pods, and a sensation that it is propelling you forward with every step. One tester ran a 3:12 marathon PB in it despite never racing further than 10K in the shoe beforehand, and found it incredibly enjoyable over the full distance once an initial arch-related discomfort faded around 5K.

The Endorphin Pro 3 feels noticeably different. It does not have that obvious bounce, but it feels more natural on the run, with four of five recent PBs set in the shoe. The defining characteristic is how smooth the Speedroll technology makes each stride. It also feels lighter and more nimble than the Alphafly, and it works at a wider range of paces, whereas the Alphafly almost demands you commit to cruising mode.

兩款鞋的老化情況

One subtle but important difference is how the midsole changes over time. The Alphafly 1 holds its feel remarkably well; a pair with around 300K on it feels similar to a brand-new shoe. The Endorphin Pro 3 softens up noticeably, becoming a bit mushy after roughly 140 to 200K, and a fresh pair felt firmer and better for hard running. Neither change seems to affect performance much, but some runners would actually prefer to race in a new Pro 3 rather than a broken-in one.

比賽日該選哪一款？

For pure racing, the Alphafly 1 edges ahead for one of us, largely because of that energetic, propulsive ride, while the Endorphin Pro 3 is the more accessible shoe that will work for more people. The Alphafly’s intrusiveness means some runners simply do not get on with it; one tester even abandoned it before a planned marathon because it nagged his calves, despite a 2:29 marathon PB previously run in the shoe. If you have unlimited choice and limited knowledge of what suits you, the Pro 3 is the safer recommendation. The Pro 3 also doubles as a superb relaxed long-run and training shoe, arguably the most forgiving super shoe if your marathon day goes badly.

性價比與供應情況

At list price, the Alphafly 1 costs £270 in the UK or $275 in the US, while the Endorphin Pro 3 comes in at £210 or $225. In practice the Alphafly is now widely discounted in sales, which changes the calculus considerably, though as an older model it is not always easy to find in your size. If you can land a genuinely good deal on the Alphafly, it remains a top-tier racing pick; otherwise the Pro 3 is the easier recommendation at full price.

結論

Both shoes are excellent, but they suit different runners. The Saucony Endorphin Pro 3 is the best all-rounder: smoother, lighter on the foot, more natural at any pace, and easier to live with. The Nike Alphafly 1 is the more explosive race-day weapon with better shape retention over its life, and at sale prices it represents real value. Pick the Alphafly if you want maximum race-day pop and can handle a less forgiving fit; pick the Pro 3 if you want one carbon shoe that does nearly everything well.
