Aloe isaloensis grows stem-forming and branched from the base. The upright, spreading or prostrate trunks are up to 30 centimeters (rarely up to 50 centimeters) long and 8 to 10 millimeters (rarely up to 12 millimeters) thick. The ten to 14 rather loosely arranged leaves , which persist on the top 10 centimeters of the trunks, are linearly narrowed. The gray-green leaf blade is 13 to 20 inches long and 1 to 1.3 inches wide. The firm, greenish to light brown teeth on the leaf margin are 1 to 1.5 millimeters long and are 5 to 10 millimeters apart. The indistinctly striped leaf sheaths are 5 millimeters long. The very abundant leaf sap is yellow-orange in color.

Inflorescences and flowers

The inflorescence is simple or consists of up to five branches. It reaches a length of 30 to 50 centimeters. The loose, cylindrical, slightly pointed grapes are 10 to 14 centimeters long and 4 to 5 centimeters wide. The deltoid bracts have a length of 3 millimeters and are 1.5 millimeters wide. The scarlet flowers are on 6 to 7 millimeter long peduncles . The flowers are 22 millimeters long and briefly narrowed at their base.
