Summary of Significant Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements contained in this report are unaudited. In the opinion of management, the condensed consolidated financial statements include all normal, recurring adjustments necessary for a fair presentation of the results for the interim periods of the fiscal year ending February 3, 2018 and of the fiscal year ended January 28, 2017. Certain items included in these statements are based on management’s estimates. Actual results may differ from those estimates. The results of operations for any interim period are not necessarily indicative of the results expected for the year. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Notes to Consolidated Financial Statements contained in Foot Locker, Inc.’s (the “Company”) Form 10-K for the year ended January 28, 2017, as filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 23, 2017.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers. The core principle of this amendment is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09, as amended by ASU 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20, is effective for annual reporting periods beginning after December 15, 2017, and interim periods therein. These ASUs can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption. The Company expects a change in the timing of recognizing gift card breakage, sales relating to shipping and handling for undelivered orders, and a change in timing for the recognition of expenses related to direct-response advertising costs. In addition, we expect a balance sheet reclassification from inventory to other current assets relating to our right to recover products for our sales returns, as well as a change to the accounting for our unredeemed rewards for our loyalty program as a reduction to sales instead of recording the charge to cost of goods sold. Although we are in the process of finalizing the quantification of the effects on the areas discussed above, we currently do not expect the adoption will significantly affect our consolidated statements of operations, financial position or cash flows. The Company expects to adopt the provisions of this standard using the modified retrospective method, which requires a cumulative effect adjustment to the opening balance of retained earnings on the date of adoption. In February 2016, the FASB issued ASU 2016-02, Leases. This ASU requires lessees to recognize a lease liability and a right-of-use asset for all leases, as well as additional disclosure regarding leasing arrangements. This standard will be effective for fiscal years beginning after December 15, 2018, including interim periods therein, and requires a modified retrospective adoption, with earlier adoption permitted. The Company does not expect to adopt this ASU until required and is evaluating the effect of this guidance. The Company has historically presented a non-GAAP measure to adjust its balance sheet to present operating leases as if they were capital leases. Based upon that analysis and preliminary evaluation of the standard, we estimate the adoption will result in the addition of $3 billion to $4 billion of assets and liabilities to our consolidated balance sheet, with no significant change to our consolidated statements of operations or cash flows. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. ASU 2016-16 requires recognition of income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. This ASU is effective and will be adopted by the Company for annual reporting periods beginning after December 15, 2017, including interim periods therein. The amendments in this update should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. Upon adoption, a company would write off any income tax effects that had been deferred from past intercompany transactions involving non-inventory assets to opening retained earnings. In addition, an entity would record deferred tax assets with an offset to opening retained earnings for amounts that entity had previously not recognized under existing guidance but would recognize under the new guidance. Based on deferred tax amounts related to applicable past intercompany transactions and the foreign exchange rates as of October 28, 2017, we expect the adoption will result in an increase in deferred income tax assets of approximately $40 million to $45 million. Other recently issued accounting pronouncements did not, or are not believed by management to, have a material effect on the Company’s present or future consolidated financial statements. Recently Adopted Accounting Pronouncements In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 simplifies the accounting for share-based payment transactions, including tax consequences, forfeitures, and classifications of the tax related items in the statement of cash flows. The Company adopted ASU 2016-09 during the first quarter of 2017. Amendments relating to accounting for excess tax benefits and deficiencies have been adopted prospectively. For the thirteen and thirty-nine weeks ended October 28, 2017, the Company recorded excess tax benefits related to share-based compensation awards of $2 million and $9 million, respectively, to the income statement, within the income tax provision, whereas such benefits were previously recognized in equity. Also, in the diluted net earnings per share calculation, when applying the treasury stock method for shares that could be repurchased, the assumed proceeds no longer include the amount of excess tax benefits. This ASU also requires that we present excess tax benefits or deficiencies as operating activities in our condensed consolidated statement of cash flow. As a result of adopting this change retrospectively, we reclassified excess tax benefits of $16 million which were previously classified as cash flows from financing activities to operating activities for the thirty-nine weeks ended October 29, 2016. Additionally, the presentation of employee taxes paid to taxing authorities for share-based transactions of $6 million, previously classified as cash flows from operating activities, were reclassified to financing activities for the thirty-nine weeks ended October 29, 2016. The Company has made a policy election of recording forfeitures as they occur instead of estimating forfeitures using a modified retrospective approach. The cumulative effect of this change was not significant. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total cash, cash equivalents, and amounts generally described as restricted cash and restricted cash equivalents when reconciling the beginning-of-period and end-of-period total amounts. This ASU is effective for annual reporting periods beginning after December 15, 2017 including interim periods therein. The Company has adopted this ASU as of the first quarter of 2017. Accordingly, we restated our cash and cash equivalents balances in the condensed consolidated statements of cash flows to include restricted cash of $28 million as of October 29, 2016 and $27 million as of both January 30, 2016, and January 28, 2017. Please see Note 5, Restricted Cash, for a reconciliation of cash and cash equivalents as presented on our condensed consolidated balance sheets to cash, cash equivalents, and restricted cash as reported on our condensed consolidated statements of cash flows
