Smile Sealing cracks in basement walls

Hello everyone,

Does anyone know of a good product to seal cracks in a concrete block foundation? There are small cracks (less than 1/16 of an inch) throughout the basement. MOST of the cracks run along the mortar holding the blocks together, but in some place the cracks run straight down the wall through the blocks as well (as in, through the middle of the blocks). Water does not seep through these cracks (in some areas, in the winter, air does). I cannot find anyone at any type of hardware store to help me. If anyone knows of a good product (or if you have any advice), PLEASE HELP! The house is a Cape Cod, about 50 years old. I live in upstate New York (cold!). Thanks in advance---
