A floor mat having a base that includes a plurality of alternating fibrous strips and impervious strips and surrounded by a frame. The base is substantially continuous across its entire width and length, having no openings from its upper surface through to its lower surface. The impervious strips include a plurality of spaced apart rows of spaced apart bosses. The gaps formed between the spaced apart bosses become closed-bottom wells in which water, snow and particles of dirt scraped from the underside of shoes can accumulate.
