5. Presence, on at least one foot, of a full-thickness ulcer for at least 4 weeks (location below the malleola).
6. Neuropathy confirmed by insensitivity to monofilament (Semmes-Weinstein 5.07 monofilament according to diagnosis criteria presented in appendix 05).
7. No ulcer should present a moderate or severe infection at baseline. Concomitant treatment with systemic antibiotics at baseline is accepted if all ulcers meet none of the criteria defining moderate or severe infection.
8. All ulcers are appropriately debrided (less than 10% black tissue covering wound area on a colorimetric scale, adequate removal of hyperkeratosis).
9. All ulcers are of Grade 1 or 2 of the Wagner classification.

10. Ulcers should meet one of the following criteria:

    If only one ulcer is present, its largest diameters has to be ≥1 cm or this ulcer is categorized as grade 2 according to Wagner classification If more than one ulcer is present, the sum of all largest diameters has to be ≥2 cm or one ulcer is categorized as grade 2 according to Wagner classification

11. For both legs: ABPI ≥0.6 and <1.3 AND ankle systolic pressure ≥70 mmHg or systolic toe pressure ≥50 mmHg or TcPo2 ≥30 mmHg (decubitus).

    If ABPI ≥1.3, patent femoral artery inflow should be confirmed by digital angiography, magnetic resonance, or CT angiography or doppler ultrasonography <6 months before randomization.

12. Patient compliant to one of the accepted off-loading system.

Exclusion Criteria:

1. Previous history of major amputation (cf. § 10.3.3.2 for definition) or planned major amputation within the first month after randomization.
2. Revascularization procedure of lower leg, or any other treatment (e.g. neurostimulation) of any leg <8 weeks before randomization.
3. Patient unable to be treated with one of the accepted type of off-loading system.
4. Active Charcot foot.
5. Presence of any ulcer with evidence of skin cancer.
6. Presence of another chronic wound (i.e. present for 4 weeks or more) not involving the foot or involving the foot but extending above malleolus.
7. Patient suffering from any known active malignancy, other than basal-cell carcinoma and cervical carcinoma in situ, requiring any general, local, surgical or radiation therapy.
8. Patient suffering from severe morbid obesity (BMI ≥50 kg/m2).
9. Severe hypertension with systolic blood pressure ≥180 mm Hg or diastolic blood pressure ≥110 mm Hg (measured at two occasions separated by a 4 week period in a patient sitting for at least 5 min).
10. Patient with a severe comorbid disorder, not expected to survive more than 12 months
11. Acute cardiovascular events (e.g. myocardial infarction, stroke, recent coronary intervention) within 3 months before randomisation
12. Patient who are in the exclusion period following a previous participation to another trial or who are currently participating to any concomitant study with any drug or device.
13. Known intolerance to the tested medical device.
