足部長時間處於濕冷環境, 造成皮膚皺摺, 發紅, 起水泡, 皮膚細胞死亡脫落.

壕溝足也會引起足部各種感覺異常: 冰冷, 沉重, 麻, 刺痛, 受熱時疼痛, 搔癢

 

濕度的影響比溫度更大. 在沙漠地區也可能發生.

嚴重的壕溝足可能造成嚴重起水泡, 永久性神經損傷, 皮膚潰瘍, 使得病患無法正常行走, 甚至造成遠端肢體壞死, 需截肢

治療: 脫掉濕襪子, 保持足部溫暖清潔乾燥

以往針對壕溝足發展出各式各樣的治療(沒有研究顯示哪個治療比其他的更好), 但初步治療如果無效, 發生壞疽之後, 還是需要手術治療.

阿佑之前爬奇萊北壁的時候發生壕溝足, 他說足底麻痛一個月

我之前跟泌珠開的大小鬼湖隊伍(後來撤退)也發生壕溝足, 原因是當天走路的時間比較長, 一開始穿雨鞋, 到達林道之後換涼鞋, 沿途幾乎都是小跑步, 下山之後發現皮膚皺摺變形, 腳趾跟腳趾幾乎黏在一起, 後來也麻痛很多天. 

Early on, bedrest was recommended, and the application of numerous different agents was tried at one time or another. Among these included a mixture of lead and opium, alcohol of different types, mercuric chloride in alcohol, tincture of iodine, oil of wintergreen, picric acid, and chloral hydrate mixed with camphor. Some powders were also used including boric acid, starch, zinc, and salicylic acid. Radiant heat, complex methods of massage, and even different types of electrical stimulation were tried in treating trench foot when the initial treatments failed.
