PER CURIAM.
      Olando Juwan Thomas appeals the district court’s1 adverse grant of summary
judgment on his 42 U.S.C. § 1983 complaint. After de novo review, see Beaulieu v.
Ludeman, 690 F.3d 1017, 1024 (8th Cir. 2012), we reject Thomas’s arguments for
reversal as follows.

        We agree with the district court that Thomas did not create a genuine issue of
material fact as to whether Lt. D. Davis was deliberately indifferent, as Thomas’s
medical authorization did not restrict him from work or from wearing sandals at work,
and he did not submit evidence of the work environment or risks of injury from
working in such shoes. See Fed. R. Civ. P. 56(a); Farmer v. Brennan, 511 U.S. 825,
834, 837-38, 847 (1994) (official violates Eighth Amendment if he knows of and
disregards substantial risk of serious harm to inmate health or safety); Nelson v. Corr.
Med. Servs., 583 F.3d 522, 528-29 (8th Cir. 2009) (en banc) (outlining two-prong
deliberate-indifference test); Choate v. Lockhart, 7 F.3d 1370, 1374 (8th Cir. 1993)
(officials are deliberately indifferent when they knowingly compel prisoners to
perform physical labor that is beyond their strength, dangerous to health, or unduly
painful; mere negligence or inadvertence, however, does not satisfy deliberate-
indifference test). Thomas also failed to establish supervisory liability against Warden
James Banks, see Williams v. Davis, 200 F.3d 538, 538-39 (8th Cir. 2000) (per
curiam) (absent constitutional violation, there is no basis for § 1983 liability against
supervisors); and his allegation that Banks improperly investigated his grievance
failed to state a claim, see Buckley v. Barlow, 997 F.2d 494, 495 (8th Cir. 1993) (per
curiam) (prison officials’ failure to process or investigate grievances, without more,
is not actionable under § 1983). The magistrate judge properly entered final judgment
under 28 U.S.C. § 636(c) without first offering Thomas an opportunity to object, see
Roell v. Withrow, 538 U.S. 580, 585 (2003) (referral under § 636(c) gives magistrate
judge full authority over dispositive motions, conduct of trial, and entry of final

      1
        The Honorable Joe J. Volpe, United States Magistrate Judge for the Eastern
District of Arkansas, to whom the case was referred for final disposition by consent
of the parties pursuant to 28 U.S.C. § 636(c).

                                          -2-
judgment, without district court review); and properly entered final judgment without
sua sponte allowing Thomas to amend his complaint.

      The judgment is affirmed.
